Synthesis,characterization and the biodegradation of the comb-type poly(4-hydroxyl-ε-caprolactone-co-ε-caprolactone)-graft-poly(L-lactide)

摘要

@@To combine good permeability of PCL and good degradability of PLLA, and copolymerization and blending of PCL and PLA have been widely applied. It is difficult to synthesize the fully biodegradable graft aliphatic polyesters because it is hard to chemically attach active molecules onto these polyesters. So far most methods are random/block copolymerization or blending, no PCL/PLLA graft copolymers were reported as we know.
