"The research described in this thesis focused on the development, fabrication and characterization of soy based plastics, coatings, and foams. The rapid depletion of the known petroleum reserves has spurred considerable interest in renewable resources derived plastics. Soybeans because of their abundant supply and relative low cost hold considerable potential as a source of different types of plastics. Natural polymers and lipids present in soybeans can be converted into functional plastics for a wide range of applications.
Present research involved conversion of soybean oil into an epoxidized soybean oil, which was then transesterified to yield epoxidized allyl ester of soybean oil or epoxidized allyl soyate (EAS). EAS was used for obtaining three types of plastics. It was combined with soy protein isolates (SPI) to develop functional plastics. The plastics were characterized for mechanical and thermal properties. The properties were compared with SPI - glycerol based plastics. The EAS-SPI plastics were found to be vastly superior to SPI-glycerol plastics in terms of mechanical and thermal properties as well as in the environmental stability.
EAS was also used as resin for beverage can coatings, these coatings exceeded industrial requirements for curing characteristics and adhesion. The coatings did not impart any off flavors or other negative attributes to the beverage stored with the EAS coated coupons for extended periods. The EAS also proved be a good resin for obtaining epoxy foams Compression and shear characteristics and thermal conductivity of the foams show that foams hold high potential in applications which require high strength foams"--Abstract, page iii.
