Photo-crosslinkable, fumaric acid monoethyl ester-functionalized poly(trimethylene carbonate) oligomers were synthesized and copolymerized with N-vinyl pyrrolidone (NVP) and vinyl acetate (VAc) to form biodegradable polymer networks. The copolymerization reactions were much faster than homopolymerization of the fumarate end-groups of the macromers. The hydrophilicity of the networks could by varied...
Biodegradable polymer networks were prepared from fumaric acid derivatives of oligomeric esters. Photo-crosslinkable macromers were prepared by reacting star-shaped hydroxyl-group terminated lactide, ε-caprolactone and trimethylene carbonate based oligomers and fumaric acid monoethyl ester in the presence of N,N-dicyclohexylcarbodiimide and 4-dimethylamino pyridine at room temperature. The functionalization...
