The degradation and recycling of thermoset materials are major sustainability challenges. In straight-chain polymers, the molecular weight significantly affects its properties, whereas. Examples of thermosetting plastics and thermoplastics. DGEVA and DGEGD thermosets were compared to those of the cured DGEBG and commercially available thermosets to determine the effect of the methoxy moiety. thermoplastic vs thermoset plastic. Wax thermostats use a little plug of wax inside a sealed chamber. 2 days ago · Thermosets; Europe - Virgin; Europe - Recycled; Europe - Feedstock; Custom . Covalent adaptable networks (CANs) are a type of polymer material that closely resemble thermosetting polymers (thermosets). simply reflects weight of the atoms and how many are packed into a given volume. The term thermoset describes a polymer-based material that is insoluble and non-melting. The molecules of thermosets can react freely to provide covalent bonds; thus, the cross-linking is gained in one gigantic molecule among the polymer. Bakelite. Including over 300 case studies, the Handbook is organised by building type and concentrates very much on practical examples. An example of this is old tires, which, after this processing, are used as fillers in covering asphalt and concrete. 1. Silicon is an excellent example of a thermoset that has a wide range of applications, its most. For example, Rothrock and co-workers reported recyclable high-performance epoxy thermosets cured by 4-aminophenyl disulfide and a commercial epoxy oligomer (diglycidyl ether of bisphenol A, DEGBA) [96]. Thermosetting molding compounds (thermosets) that undergo a chemical reaction or cure (called polymerization or molecular growth) during the molding operation. . Density. Cured thermoset resins may soften when heated, but do not melt or flow. Thermoset plastics, started getting recycled from 2014. They always used in conjunction with reinforcement and fillers. Thermosets vs Thermoplastics are very different from one another. Unlike thermoplastics, which can be melted and reformed. Examples of Thermosets. So whilst the mechanical recycling of thermoset materials has been examined by a number of researchers for subsequent use in both thermoset (Hulme and Goodhead, 2003; Palmer et al. 3. Because they are made up of bi-functional and tri-functional. Epoxy (EPX 82): An additive material developed by Carbon for its DLS process. Although the title of this chapter is focussed on the “aerospace” industry, this is of course not monolithic, and, for example, the products of the civil and military sectors are subject to different demands and employ a range of diverse polymers. Common examples of thermosets include epoxy, silicone, and polyurethane. Example of a thermoset print from an SLS 3D printer using Tiger Coatings’ new powder [Source: Google Patents. Thermosetting Plastic is high in molecular weight. This mechanism is opposite to thermoplastics. In short, thermosets and their composites can be found in all. It is also important to note that there is the possibility of a material to be thermoplastic and thermoset. Thermoplastics. Drilling down – what determines modulus and density? The conventional starting point for interpretation of modulus and density is the “hard sphere” model, with atoms of one type packed into a crystal. Thermoplastic is more common; some examples of thermoplastic products are plastic bags, plastic bottles, spectacle frames and mobile. Thermosets, also known as duromers. Our production capabilities consist of compression molding, transfer molding, and injection molding of both thermoset and thermoplastic resins. Thermoset polymers have a higher temperature resistance, both hot and cold – they strengthen when heated and do not warp in extremely cold temperatures, but cannot be remolded. See moreExamples What is an example of a thermoset plastic? Thermoset plastics and polymers include epoxy, polyurethane, phenolic and silicone as well as materials such as. Thermosets provide an alternative approach to when complex and geometric shapes cannot be achieved through metal fabrication. Thermoset polymers have covalent bonds linking the polymer chains in three dimensions. Thermosets can be formed and hardened only once. The process of curing changes the resin into an infusible, insoluble polymer network, and is induced by the action of heat or suitable radiation often under high pressure, or by. Common products and applications that are made from thermoset plastics include construction equipment panels, electrical housings and components, insulators, cell tower tops, heat shields, circuit breakers, agricultural feeding troughs, motor components, and disc brake pistons. In addition, plastics possess attractive and indisputable features. Menard 2 . Epoxy, polyurethane, and silicone are examples of thermoset plastics, as are materials such as polyester. 7 Conclusions. The different behaviour of thermosets and thermoplastics when heated. Hope this article is helpful to you. Here are the 5 Main differences between them: Synthesizing. This feature makes thermosets well adapted to applications involving elevated temperatures. Polyethylene, for example, is formed by polymerizing ethylene molecules. Thermoplastics include polyethylene and polypropylene, which are used for plastic bags and other single-use plastics like food wrappers. Both thermosets and thermoplastics are good insulators, but again, look at the specific material. 5. 1. Bakelite. They are abrasion-resistant, flexible and tough offering excellent. In addition, some materials such as polyester can occur in. MIT chemists have now developed a way to modify thermoset plastics that allows them to be more easily broken down without compromising their mechanical strength. Additionally, the storage form of thermosets polymer is liquid, and it is in a large container or tank. Examples of these materials are steering wheels, gaskets, car bumpers, windshields, door panels, and any other automotive and electrical parts. Thermoplastics and thermosets are two distinct categories of polymers, which are large molecules composed of repeating smaller units called monomers. Here are the 5 Main differences between them: Synthesizing. For example, only the preparation of bio-based monomers or only one type of thermosets (epoxy or polybenzoxazine or unsaturated polyesters) was reviewed. They are a form of polymer that is hardened by the process of curing. The typical procedure for bio-based thermosets synthesized from renewable resources is illustrated in Fig. 6 Advanced materials based on thermosets. The Examples of Thermosetting Polymers. THERMOSET PLASTIC. 2 Overview of. Some thermosets have good mechanical properties and show high ionic conductivity, which can be synthesized from ionic liquid epoxy monomers. Examples of thermoplastic polymers include: 1. Thermosets generally yield higher chemical and heat resistance, as well as a stronger structure that does not deform easily. Thermosets, by definition, is a polymer which becomes irreversibly hardened upon being cured. When looking at engineering applications for thermosets, Martin Starkey, director of Gurit Automotive said it best at a recent Automotive Composites Conference and Exhibition (ACCE). Cost It is also important to note that there is the possibility of a material to be thermoplastic and thermoset. Thermosets are also called duromers or thermosets and are plastics that retain their state and shape after curing. For example, elastomers make up the gaskets, seals, hoses and dampeners that are used in tractors and other agricultural vehicles. Franck 10/04 V1 ture of the processes involved and the rheological changes in-herent in these. Thermosets are involved as binders even when insulation is the commonly encountered fiberglass, and a formaldehyde-based or a water-based acrylic formulation is sprayed on the glass filaments in the process of insulation manufacture. As the temperature rises, the wax melts and changes from solid-state to a liquid state. A thermosetting plastic is a kind of polymer that, when heated, transforms into an irreversibly stiff state. When it comes to novel biomaterials and biomedical devices, thermoplastic and thermosetting polymers represent a suitable choice, mainly thanks to their intrinsic mechanical behavior, chemical stability, physicochemical versatility, and functional tunability. Thermosets have excellent ‘flow’, which makes for easier molding and shorter cycle times. For example, phenols can be used for the synthesis of benzoxazine and epoxy resins, while carboxylic acids are suited to prepare epoxy resins and unsaturated polyesters. Examples: Thermosetting polymers are Bakelite, vulcanized rubbers, epoxy resin, vinyl ester resin and polyurethane etc while thermosetting plastic examples are Teflon, Acrylic, Nylon etc. Thermoplastics depend on “addition polymerization process”. This is in contrast to a thermoplastic material, which is generally soluble and can be melted. An Introduction Compression molding is a common polymer manufacturing process for thermosets, thermoplastics, as well as elastomers and natural rubbers. If each mobile telephone has on average two printed circuit boards, a case, a screen, a keypad, a battery pack, an antenna array, and a speaker, this means that just in this application, there are probably in excess of 35 billion thermoset components—by any measure—a phenomenal example of the scale of thermosets. Thermosets are critical to the manufacture of automobiles, airliners such as the Boeing 787 and the Airbus 350, most sports equipment, furniture, appliances, military equipment and weapons…the list is virtually endless. 2. Healthcare facilities use a huge variety of elastomers at every level. Thermosetting polymers. Elastomers are often chosen for sterility, biocompatibility and low leaching levels. A thermosetting plastic is a polymer that irreversibly becomes rigid when heated. The list of synthetic biodegradable polymers used for biomedical application as scaffold materials is available as Table 1 in Ref. The first plastic ever made, Bakelite, is an example of a thermoset. Curing is initiated by heat, radiation, high pressure, or the addition of a catalyst. Toughening is achieved by producing a dispersion of this second phase inside the network. Examples of such additives include (i) nanoparticles, (ii) reactive polymers, and (iii) block copolymers. Thermosets derived from renewable sources have played an important role in research over the last few decades. Nevertheless, it is. Examples of one-part nursing diagnosis statements include: Readiness for enhanced coping; Rape Trauma Syndrome; Two-Part Nursing Diagnosis Statement. The thermoplastic formation process cools the mold for solidifying the molten plastic that is injected. An example of self polymerization is theThe decoration of epoxy precursors or hardeners with acetal groups is therefore highly interesting for the design of recyclable and degradable epoxy thermosets (Scheme 6b & 6c). Vodafone and Mannesmann (1999) - $202. Thermoset resins, which cure at room temperature like unsaturated polyester, vinyl ester, epoxy, etc. 2. Thermoplastics offer versatility for various stress levels and environments, with examples like polyethylene, PVC, and nylon. Another difference of Thermosets from thermoplastic materials is the process used to manufacture components. One you may be familiar with is epoxy, where two chemicals are mixed to cause a final reaction. The egg begins as a liquid (a colloid, actually, but let’s not quibble) which, when dropped in a warm pan, becomes a solid. This book focuses on synthetic thermoplastic polymers that are used for development of plastics materials. Thermosetting plastic ( once formed in the required shape- thermoset plastic cannot be remelted, if reheated it will char and burn), Thermoset plastics usually cater to niche applications, mainly in heat resistance. Shows reason or purpose. A common example of this is seen with Silly Putty®. The typical procedure for bio-based thermosets synthesized from renewable resources is illustrated in Fig. Vulcanized Rubber. Please contact us today by calling 919-404-2080 or filling out our form below to discuss your custom plastic manufacturing needs. Some of the applications that we use polyurethane foams; We use rigid foams in refrigerator walls as a thermal insulators. Polyesters, vinyl esters, epoxies, phenolics, and polyamides are the best examples of thermosets. The chemical name. Little John was very happy; for he was only seven years old. Examples of Thermosetting Plastic 1. Thank you for giving your best every day. Modifying polymers, thermoplastics and thermosets. First some reminders from section 7. Examples include polyurethanes, polyesters, epoxy resins and phenolic resins. As an example, the intrinsic brittleness of most high-T g thermosets can be reduced using rubbers, thermoplastic polymers, core-shell particles, or block copolymers as additives of the initial formulation [16], [17]. It is organised by building type and concentrates very much on practical examples. 7. Thermoset precursor materials may be of low molecular weight, and some after mixing will flow and crosslink at room temperature [1] – allowing for relative ease to process. Common examples of modal verbs include can, should, and must . PVC – Rigid. Examples of thermosets include polyesters, phenolics, silicones, and epoxies. Although thermoplastic resins are the cheaper option between the two classes, thermosets offer more benefits than thermoplastics. Thermosets are solidified by irreversible chemical reactions, in which the molecules in the polymer “cross-link,” or form connected chains. For example, the epoxy business that used to be part of Shell (the well-known “Epon” family of resins, as well as “Epikote”, “Epirez” and “Epikure” resins) is now Resolution. , skin, veins, heart, and lung tissue). They are amorphous and considered to have infinite molecular weight. Examples of thermosets include epoxy resins, phenolic resins, and polyurethane. This means that unlike. This chapter focuses on some aspects of the chemistry of epoxy polymers because it provides examples of both step-growth. Thermosets are a different kind of plastic where a chemical reaction occurs once to solidify the material, and it cannot be reversed. DMA results indicate that the presence of the methoxy lowers the glass transition temperature (T. Thermoplastics and thermosets are both incredibly common in many industries and can be found in a wide variety of products. The comonomers, representative of cellulose-derived (DBI). These are produced by the polymerization process in which the material is subjected to certain heat and pressure. Argumentative essay formula & example. a way of helping…. This is a good example of what I mean when I say not every segment of the economy will experience a soft landing. Bio-based thermoset resins are considered important candidates for sustainable development since they present the potential to reduce both CO 2 footprints and the dependence on petroleum. The resins are classified as novolac and resole: the former being catalyzed in acid and requiring a curing agent (two. As the material cools and hardens to the. , contact lenses, prostheses, catheters), and parts of living organisms (e. The most commonly known thermoset example is Bakelite, which plays an important role in plastics’ history. Some thermosets have good mechanical properties and show high ionic conductivity, which can be synthesized from ionic liquid epoxy monomers. Once cured, their polymers can no longer be dissolved. Covalent adaptable networks (CANs) represent a transition material combining favorable features of thermosets and thermoplastics. The thermosets show both good stability to extreme conditions (e. In general, because EP has a three-dimensional random network, it possesses thermal properties similar to those of a typical heat insulator. Thermoplastics, on the other hand, can be heated and remolded over and over again. This is an obvious distinction between thermoset and thermoplastic materials. The ‘aerospace’ industry can be divided into civil and military. What does thermosetting examples? However, check thermosetting examples at our online dictionary below. An example for a soft acrylic TPE. 2. Clive B. Cure will usually involve the use of heat, radiation, or light (photoinitiation), moisture, activators or catalysts. , are. . Thermoset matrix systems dominate the composites industry because of their reactive nature and ease of impregnation. , masks, inhibits, or suppresses) the expression of a particular gene ratio. The main differences between thermosetting and thermoplastic plastics lie in their behavior at elevated temperatures: while thermoplastic polymers can be remolded and heated as many times as desired, thermosetting polymers can be remolded and heated only once. While both types of materials can be classified as polymers, the primary difference lies in their structures. Thermosets can effectively prevent the leakage of electric current, hence protecting the equipment and operators from electric faults. Advantages of Thermosets. These advantages are high ductility, toughness, etc. Phenolics, epoxies and unsaturated polyesters are typical examples of thermosets. The list of synthetic biodegradable polymers used for biomedical application as scaffold materials is available as Table 1 in Ref. Modal verbs are used to express certain hypothetical conditions, such as advisability, capability, or requests (there’s a full list in the next. In addition, thermosetting examples, such as epoxy, phenolics, silicones, etc. Downloaded from organic. Thermosetting depend on “condensation polymerization process”. Thermosets can also be molded into complex geometry through the fabrication process. Examples of what to type: Full or partial part number: “S. *Properties and performance of thermoplastics, polymer blends. The degree of crosslinking in a thermoset is a critical parameter that has a major influence on the mechanical strength and visco-elasticity of the material. Figure 1. Parameterizing force. . Once cooled and hardened, these plastics retain their shapes and cannot return to their original form. As an example, the intrinsic brittleness of most high T g thermosets can be reduced using rubbers, thermoplastic polymers, core–shell particles or block copolymers as additives of the initial formulation (Pascault and Williams, 2000, Pascault and Williams, 2010). In order to reduce the ecological impact of plastic without. Thermoset adhesives are crosslinked polymeric resins that are cured using heat and/or heat and pressure. Thermoplastics differ from thermosetting polymers. 4. 1. Bathtubs and shower stalls; Luggage; Computer keyboard keys; 3D models and product prototypes. Monomers and oligomers can be self-polymerized or polymerized with a co-reactant or curing agent. The synthesis of bio-based recyclable thermosets such as the Schiff base CFRP offers a clear example of a closed-loop recycling solution and low energy-consuming process, where both high flame retardancy and sustainability are considered in the fabrication of carbon fiber reinforced polymer composites. Thermosets are often used in combination with glass or carbon fibre for larger objects, such as boats or gliders. Thermoplastic polymers can be molded, melted, and remolded without altering its physical properties [43]. Thermosets examples The broadest classification for plastics is the old thermoplastic and thermosetting . Thermosets. Thermosets are usually stored in liquid form in large containers. These properties include non-conduction, low density, low porosity. The high rate of recycling thermoplastics makes it convenient to be used in composite materials. Examples of common thermoplastic resins and products manufactured with them include: PET (water and soda bottles) Polypropylene (packaging containers). These polymers have the capacity to undergo enormous elongation due to elastic deformation (up to 1000%),. Appreciation Examples on Work Ethics & Attitude & Values. Thermosetting polymer, often known as a thermoset or thermosetting plastic, is a polymer made up of highly branched molecules or a cross-linked structure. These. The use of thermoset plastics has a number of advantages. Figure 1. Upon heating, thermosets remain solid until the temperature reaches the point where it begins to degrade. Plastics comprise around 10% of solid waste in Australia. Because of their high melting point and poor solubility in. Although thermosets can only be shaped once, they have higher mechanical and thermomechanical properties than thermoplastics [199]. Thermosets are large molecular weight polymers that are an appealing alternative to both thermoplastics and other traditional materials, such as metals and wood, due to their structural and aesthetical advantages, cost and workability []. The different behaviour of thermosets and thermoplastics when heated arises from their chemical structures. A good example of a thermosetting polymer is vulcanized rubber. One might also refer to this type of substance as a thermoset or a thermosetting polymer. Thermosets are polymers that harden when heated up and cannot be recycled. Thermosets from renewable sources have been the research focus of last few decades. Duroplast. Thermoplastics Examples What is an example of a thermoset plastic? Thermoset plastics and polymers include epoxy, polyurethane, phenolic and silicone as well as materials such as polyester (which can also occur in a thermoplastic form). Thermoset plastics contain polymers that cross-link together during the curing process to form an irreversible chemical bond. 4. Subsequent chemistries have been developed to produce thermosets that process more easily and are more heat resistant. 4 Elastomers The elastomers are provided with an intermediate structure, in which there is also some crosslinking. 08. Bakelite was the first thermoset plastic that was synthesized from synthetic components. Examples of thermosets include epoxy, phenolic, and melamine. Some of the applications that we use polyurethane foams; We use rigid foams in refrigerator walls as a thermal insulators. Thermosets and the Environment. , are suitable for high- and low-gloss surface finishes. Unlike thermoplastic polymers. These materials are made by heating up small pellets of plastic until they melt, then molding them into the desired. A) Give three examples of products that must be made from thermoplastic and same for product that must be made of thermosets. They will decompose when reheated. Thermosets: Polyurethane and epoxy are common thermosets. Thermosets are most frequently used in situations where the part must be able to withstand high temperatures. Introduction. Biopolymers can also be classified based on the ways in which they respond to heat as thermoplastics, thermosets [9], or elastomers. Thermoplastic is lower in molecular weight, compared to thermosetting plastic. Thermosets are essentially polymers possessing the ability to crosslink their inter-and intramolecular chains to form a solid polymer network (Dodiuk, 2013). and a thermoset, and comment on the molecular basis for their different properties, including crystallinity. Thermoset polymer Characteristics. Examples: Polyester resin fiberglass systems include the following components: sheet. This is accomplished using an amorphous, thermoplastic housing with threaded inserts to securely seal the electronics of the drill from its environment. Properties. cannot be reshaped by heating, they are called thermosets. By Hafsa "thermosetting examples" at online dictionary. Bryan Bilyeu 1, Witold Brostow 1 and Kevin P. The best example for such a system is epoxy/ PDMS- b -PCL- b -PS. 2. Thermoset plastics are stored in liquid form and different thermosets offer different advantages. Examples of thermosets are vulcanized rubber, Bakelite™ (used in electrical insulators), melamine (used in worktop surfaces), and epoxy resin (used as an adhesive). It is in fact a family of materials that come with a range of densities and molecular structures, each with their own. . Medical Applications. Thermosets usually are three-dimensional networked polymers in which there is a high degree of cross-linking between polymer chains. Stay Connected. 2. ) The other major advantage of thermoplastic composites is. This property. 1. While both types of materials can be classified as polymers, the primary difference lies in their structures. Common examples include epoxy resins. Thermosetting and elastomeric polyurethanes are the most important groups. In automobiles, Thermosets are utilised for producing brake pistons. Nanostructured thermosets may also be prepared by the incorporation of ABC tri-block copolymer. Some examples of thermoset polymers include: urea–formaldehyde resins, melamine–formaldehyde resins, polyurethanes, epoxy resins, phenol–formaldehyde resins, UPEs resins, polyelectrolytes, etc. filler compositions. For example, an important application is the measurement of the glass transition and the curing reaction in epoxy resin systems. Examples of Thermoplastics: Examples of Thermosets: Acrylonitrile butadiene styrene (ABS) Polycarbonate (PC) Polyethylene (PE) Polyethylene terephthalate (PET) Polytetrafluoroethylene (PTFE) Polyvinyl chloride (PVC) Polymethyl methacrylate (PMMA) Polypropylene (PP) Polystyrene (PS)Thermosets are generally less resistant to alkalis and careful choice of the resin type must be made to avoid issues which may result in premature failure. The products of these sectors are subject to different demands and employ a range of diverse polymers. about addition polymers which were discussed in some detail. Today, Bakelite products are most popular as a collectable novelty. The synthesized thermoset hyperbranched polymers (HER-HTn) reported in this study exhibit recoverability. Thermoplastic can be molded into any shape. 1 compares some of the properties and features of natural and synthetic polymers. Another example is Melamine which has a capacity to resist fire and heat much efficiently than other plastics. The most important effects that can be analyzed by DSC are the glass transition, melting behavior. And it is well known that the objective of bio-based thermosets research is to fulfill the principles of sustainable development. The curing process changes the resin into an insoluble polymer network. Toughening is achieved by producing a dispersion of this second phase inside the. Thermoplastics, on the other hand, can soften with heat. Rubber tapped from para rubber trees is a polymer of isoprene monomers. Examples and applications. Acrylic. Even your dentist relies on thermoset polymers to repair or replace your teeth. The discovery of the various cure chemistries do not represent the end of the development cycle but mark the beginning of families of. Once thermosets are solidified, they cannot be reformed or. Monomers are joined together to form a three-dimensional network in this type of polymer. This is the major difference between the two. Thermosets vs. 1,2 In particular, the diglycidyl of bisphenol A (DGEBA), a commercial epoxy resin, exhibits high mechanical strength, excellent thermodynamic properties, and favorable stability after. Amongst the various varieties of plastics, Thermosets which is widely used in electronic devices was considered as unrecyclable till 2013. 34, 35 The introduction of DCC into polymer networks enables the chemically crosslinked networks to undergo bond exchange under external stimuli, such as heat and. Thermosetting polymer: Properties: Uses: Epoxy resin (ER) Supplied as two parts, one resin and one hardener (see image) - the resin and hardener combine to create an extra-strong adhesive, good. Unlike thermoplastics that can be melted and reshaped, thermosets undergo irreversible chemical reactions during curing. Thermoset Processing Multistage Processing Quite commonly, thermosetting resins are processed in two or more stages, as, for example, are those used in the production of fiber reinforced laminates. Some common examples include: The term thermoset describes a polymer-based material that is insoluble and non-melting. Thermosets are a popular alternative to metal. For example, Stevens 148 investigated the failure of highly cross-linked random and ordered polymer networks between solid walls using CG MD. Study with Quizlet and memorize flashcards containing terms like what are the 3 different types of polymers:, What are some examples of thermoplastics?, What are some examples of thermosets? and more. The chapters describe many interesting examples that illustrate the power of thermal analysis for measuring physical properties, different types of transitions, aging, the effect of fillers and additives, and the influence of production condi-tions. Fully bio-based flame retardant epoxy thermosets. The thermosetting polymers harden throughout the moulding process and cannot be re-softened with heat. The polymers and other agents are fed into tanks or barrels, where they are heated to a liquid state and mixed. For example, the machining of thermosets usually requires sharp cutting tools, and lower cutting speeds to avoid excessive heat buildup, which can cause the material to degrade or the tool to wear prematurely. Common. 2022 Harry Brown. This chemical bond removes the risk of the product melting if heat is later applied. The next day his house becomes a portal for a daemon world. Thermoset polymers are examples of chemically cured, network-forming materials whose bulk properties depend sensitively on formulation chemistry and reaction conditions. It belongs to the polyolefins group. While this characteristic allows. The simulations relate failure strain (in tension and shear) to the shortest distance between. Nylon (Polyamide) Polyolefins. B) If "Acrylonitrile Butadiene Styrene" is used in injection molding of Lego parts. One way to explain the difference between thermoplastic and thermosetting polymers is to consider an omelet. Biopolymers are a leading class of functional material suitable for high-value applications and are of great interest to researchers and professionals across various disciplines. It polymerizes via a complex radical process and has a complex network topology. One of the most common examples of thermosets is bakelite which is relatively a bad conductor of electricity and heat. Phenolic resins, called by the tradename Bakelite ®1 after inventor Leo Baekeland, are known for their heat resistance, hardness, dimensional stability, and chemical and electrical resistance. 3. A series of materials was prepared by curing acrylated epoxidized soybean oil (AESO) and dibutyl itaconate (DBI) or ethyl cinnamate (EC) comonomers to provide examples of thermosets with a high proportion of bio-based carbon, in accordance with the principles of green chemistry.
