Abstract
BIODEGRADABLE POLYMERS FROM SESAME OIL WITH METHYL ACRYLATE AND METHYL METHACRYLATE CO-MONOMERS

Irin Sheela. C* and Begila David. S

ABSTRACT

In this study biodegradable polymers were synthesised by the polymerization of alkyd resin of sesame oil with co-monomers like methyl acrylate(MA) and methyl methacrylate(MMA). Monoglyceride of sesame oil(SOMG) was first prepared by the glycerolysis of sesame oil at 220 - 230°C. Then the resin was prepared by the reaction of the monoglyceride with cyclohexane dicarboxylic anhydride at 80°C for 2 hours. The cross linked biopolymers were prepared by the free radical polymerization of the resin with various concentration of different monomers in presence of benzoyl peroxide as initiator. The newly prepared polymers were analysed for thermal and mechanical properties. Biodegradation of the poymers were also tested by soil burial test and SEM micrographs assess surface damage and to look for the presence and nature of microbial growth. The reactions were followed by H1 NMR and FT-IR spectroscpy.

Keywords: Biodegradation, Thermal studies, Alkyd resin.
