“…This indicates that end‐functionalization by methacrylic anhydride did occur. The disappearance of the carbon–carbon double bond peak and an increase in the band –CH stretch at about 2900 cm −1 in the cured resin indicates that the crosslinking reaction of the resin had occurred. The complete crosslinking reaction was verified as shown in Figure (a); for the cured n = 3 resin, the spectrum shows no band at 1640 cm −1 and this clearly indicates that all double bonds had reacted when cross‐linked.…”

“…In recent years, renewable resources are increasingly providing sustainable platforms to substitute petroleum‐based polymers. Many research projects have shown that bio‐based resins from renewable resources can compete with or even surpass fossil fuel resources based on considerations related to cost and eco‐friendliness . The development of monomers or raw materials for these bio‐based resins (for example: soybean oils, linseed oil, or lactic acid) can enable a reduction in the use of fossil resources .…”

A bio‐based thermoset resin has been synthesized from glycerol reacted with lactic acid oligomers of three different chain lengths (n): 3, 7, and 10. Lactic acid was first reacted with glycerol by direct condensation and the resulting branched molecule was then end‐functionalized with methacrylic anhydride. The resins were characterized by Fourier‐transform infrared spectroscopy (FT‐IR), by 13C‐NMR spectroscopy to confirm the chemical structure of the resin, and by differential scanning calorimetry and dynamic mechanical thermal analysis (DMTA) to obtain the thermal properties. The resin flow viscosities were also measured using a rheometer with different stress levels for each temperature used, as this is an important characteristic of resins that are intended to be used as a matrix in composite applications. The resin with a chain length of three had better mechanical, thermal, and rheological properties than the resins with chain lengths of seven and 10. Also, its bio‐based content of 78% and glass transition temperature of 97°C makes this resin comparable to commercial unsaturated polyester resins. © 2014 Wiley Periodicals, Inc. J. Appl. Polym.

“…As alternative shell materials, poly(styrene-co-maleic anhydride) or SMA may be beneficial due to its functionality and chemical reactivity: it has a carboxyl oxygen able to interact with fatty acid groups [28], while some grades may self-organize into spherical aggregates due to their specific heterogeneous molecular structure [29]. Based on the reactivity of the fatty acids, maleination has been frequently used for the cross-linking of vegetable oils [30]. The SMA was previously used to form microcapsules from acetate or dodecanol by interfacial polyaddition with amines [31], by hydrolysis and surfactant synthesis with octadecane [32], or complex coacervation with gelatin [33].…”

“…Among them, triglyceride oils are expected as an ideal alternative chemical feedstock, since triglyceride oils, derived from plant source, such as soybean, palm, canola, and sunflower, are found in abundance in the world [4,5]. Inexpensive plant oils have been extensively used for various applications such as coatings and inks as a binder [6][7][8][9][10][11]. However, these oil-based materials did not show properties of rigidity and strength required for various applications by themselves.…”

IntroductionBio-based polymers are now moving into the mainstream and may soon be competing with commodity plastics [1-3]. Using biomass as a starting material for plastics is highly significant for reduction of greenhouse gas and fossil resource-saving in social viewpoints, which is one of the most promising solutions to problems concerning global environment and energy resources. Among them, triglyceride oils are expected as an ideal alternative chemical feedstock, since triglyceride oils, derived from plant source, such as soybean, palm, canola, and sunflower, are found in abundance in the world [4,5]. Inexpensive plant oils have been extensively used for various applications such as coatings and inks as a binder [6-11]. However, these oil-based materials did not show properties of rigidity and strength required for various applications by themselves. In some cases, triglyceride was a minor component in the polymeric materials; this was used solely as a modifier to improve their physical properties [12-18].Epoxidized plant oils are easily synthesized from the more common unsaturated oils, such as linseed, sunflower, and soybean oil, by standard epoxidation reaction [19]. Epoxidized soybean oil (ESO) and epoxidized linseed oil (ELO) are commercialized in large volumes, and have been used as an environmentconscious plasticizer for poly(vinyl chloride), chlorinated rubber, and poly(vinyl alcohol) emulsions to improve stability and flexibility. The polyols and acrylates converted from epoxidized plant oils were developed as a starting material for bio-based functional polymers [20-22]. Furthermore, epoxidized plant oils have been polymerized by ring-opening polymerization using photoinitiators, latent catalyst, and acid catalyst to produce plant oil-based network polymer [23-26].Recently, organic-inorganic green nanocomposites were developed by an acid-catalyzed curing of ESO in the presence of a silane coupling agent or an organic clay [27-31]. The mechanical properties of these plant oil-based nanocomposites increased by incorporating the inorganic moieties. Bio-based green composites were synthesized using biofiber such as kenaf, flax, and hemp as renewable compounds. Their mechanical strength was effectively improved by the incorporation of biofiber, whereas most of them showed poor flexibility due to the plant oil-based network structure [32-34].Rosin is one of bio-based materials and is obtained from the exudation of pines and conifers, which contains approximately 90% of abietic acid and its isomer. Rosin exhibits excellent solubility for organic media and compatibility with a variety of synthetic resins. Rosin and its derivatives have been used as adhesive tackifiers, and are still mainly used in those markets. In addition, they have also found other applications in printing, varnishes, paints, sealing wax, some soaps, paper sizing, etc. AbstractIn this study, bio-based polymeric materials have been developed from plant oil and rosin derivative. An acid-catalyzed curing of epoxidized soybean oil (ESO) in...
