Ageing Characteristics Of Novel Polyesters Based On Rice Bran Oil

Abstract

            Polyesters are synthesised from acrylated epoxidised rice bran oil resin with monomers such as vinyl acetate, n-vinyl 2-pyrrolidone, methyl acrylate and benzoyl peroxide as the initiator. The ageing characteristics of the newly prepared polyesters have been studied. These studies revealed that ageing characteristics of vinyl acetate and vinyl pyrrolidone based polyesters shows very good hydrolytic stability and thermally more stable than methyl acrylate based polyesters. The antimicrobial activity of polyester based on methyl acrylate is comparatively maximum zone of inhibition than the other polyesters.
