Synthesis and Characterization of Poly(Glycerol Sebacate)-co-Lactic Acid via Gamma Irradiation

Article Preview

Abstract:

The gamma irradiation was utilized to facilitate the synthesis of poly (glycerol sebacate)-co-lactic acid (PGS-co-LA). The effect of methyl methacrylate (MMA) crosslinker and varying dosage of irradiation to the structural composition and thermal properties of the synthesized PGS-co-LA was investigated. Compositional analyses of the polymer materials using infrared spectroscopy confirm the covalent formation of ester linkage. The use of methyl methacrylate enhances the formation of the characteristic bonds in the polymer structure. The intensity of these peaks increases with increasing irradiation dosage and high amount of crosslinker. The melting temperature of the PGS-co-LA becomes more negative with the incorporation of high amount of MMA.
