An acrylic epoxidized soybean oil (AESO) has been used in this study. The synthesis of the acrylic resin has been made from acrylic acid which breaks the epoxy groups of the ESO (epoxidized soybean oil). This material can be obtained thermosetting polymers suitable for use as a matrix in "green composites. The aim of this work is to develop some AESO-styrene mixtures in order to evaluate the influence of the AESO-styrene ratio in the curing process and also it is desired to obtain the resins characteristics.

Abstract In this article, five kinds of soybean oil-based polyols (polyol-E, polyol-P, polyol-I, polyol-B, and polyol-M) were prepared by ring-opening the epoxy groups in epoxidized soybean oil (ESO) with ethyl alcohol, 1-pentanol, isoamyl alcohol, p-tert-butylphenol, and 4-methoxyphenol in the presence of tetrafluoroboric acid as the catalyst. The SOPs were characterized by FTIR, 1H NMR, GPC, viscosity, and hydroxyl numbers. Compared with ESO, the retention time of SOPs is shortened, indicating that the molecular weight of SOPs is increased. The structure of different monomers can significantly affect the hydroxyl numbers of SOPs. Due to the large steric hindrance of isoamyl alcohol, p-hydroxyanisole, and p-tert-butylphenol, SOPs prepared by these three monomers often undergo further dehydration to ether reactions, which consumes the hydroxyl of polyols, thus forming dimers and multimers; therefore, the hydroxyl numbers are much lower than polyol-E and polyol-P. The viscosity of polyol-E and polyol-P is much lower than that of polyol-I, polyol-B, and polyol-M. A longer distance between the molecules and the smaller intermolecular force makes the SOPs dehydrate to ether again. This generates dimer or polymers and makes the viscosity of these SOPs larger, and the molecular weight greatly increases.

Soybean oil is one of the major vegetable oils containing more than 99% of triglycerides of saturated and unsaturated fatty acids and has become an interesting source to produce bioplastic. This study investigates the synthesis and characterization of bioplastic developed by the acrylate epoxidized soybean oil through ring opening polymerization process. The mechanical properties of the samples were characterized using Fourier Transform Infrared Spectroscopy, Thermogravimetric analysis and the physio-chemical properties of the bioplastics were studied. In this study, the bioplastic made up from soybean oil with the lowest glycerol concentration showed the best mechanical properties.

A novel rigid polyurethane foam was prepared by using epoxidized soybean oil (ESBO) instead of 50% of petrochemical polyol-835 in the B-side of foam formulation. Although there are no significant variations in density and compressive strength of ESBO-based rigid foam compared with petrochemical-based rigid foam, better thermal stability and higher melting point (of polyether section) were attained and proved by TGA, DTG and DSC analysis. Presumably, the improved characterizations could be originated from the long carbon chain of ESBO and especially the oxazolidone structure as indicated in FTIR spectrum.
