Photocurable liquid biodegradable copolymers: in vitro hydrolytic degradation behaviors of photocured films of coumarin-endcapped poly(epsilon-caprolactone-co-trimethylene carbonate).

Abstract

Coumarin-endcapped tetrabranched liquid copolymers composed of epsilon-caprolactone and trimethylene carbonate (TMC), prepared using pentaerythritol or four-branched poly(ethylene glycol) (PEG) as an initiator, were ultraviolet irradiated to produce photocured solid biodegradable copolymers. The hydrolytic degradation behaviors of photocured films were… (More)
