Photo and biodegradation of thermosetting polymers from linseed oil


Author(s): Irin Sheela. C and Begila David. S

Abstract: Photo degradation and biodegradation of thermosetting polymers prepared by the free radical polymerization of alkyd resin of linseed oil with monomers like vinyl acetate (VA) and N- vinyl 2-pyrrolidone (VP) was studied. Monoglyceride of linseed oil was first prepared by glycerolysis of linseed oil at 220-230 °C. Then the resin was prepared by the reaction of the monoglyceride formed with cyclohexane dicarboxylic anhydride at 80 °C for 2 hours. Cross linked polymers were synthesised by the polymerisation of the resin with vinyl acetate (VA) and N- vinyl 2-pyrrolidone (VP) comonomers in the presence of benzoyl peroxide as initiator. Biodegradation of the polymers were tested by soil burial test. SEM micrographs were taken to assess surface damage and to look for the presence and nature of microbial growth. Photo degradation of the polymers was studied by exposing the polymers to direct sunlight and UV light. The reaction was followed by H1NMR and FT-IR spectroscopy. The polymers prepared to be degradable and thus serve as replacement in numerous potential applications.
