- W2357228832 abstract "The enzymatic degradation of PLA-PCL random copolymers was investigated in PBS(pH 7.4) containing 0. 02%lipase from porcine pancreas(PPL).Hydrolysis experiments of the PLA-PCL random copolymers were performed in water solutions with different pH values(1.0,7.4 and 9.0) at 37℃.The weight loss,changes in the composition, molecular weight and distribution were investigated.It was found that the degradation of copolymers was accelerated via PPL catalyzing the hydrolysis of ester bond.The H-NMR data showed that the CL content decreased in enzymatic degradation,LA content decreased during hydrolytic degradation,and PLA-PCL random copolymers degraded fastest in aqueous media at pH 1.0." @default.
