Synthesis and Characterization of Crosslinked Polymers for Biomedical Composites

Abstract

Abstract Three kinds of low molecular weight unsaturated polyesters containing carbon-carbon double bonds were synthesized by the reaction of poly (ε-caprolactone) diol or D,L-lactide and glycolic acid with maleic anhydride or fumaric acid. These functionalized polymers were thermally crosslinked in the presence of radical initiator to prepare the crosslinked polymers available as a matrix resin for biomedical composites. Hydrolysis of the crosslinked polyesters was investigated in buffer solution at 37°C.
