BIMODAL MOLECULAR WEIGHT COPOLYMERS OF LACTIDE AND GLYCOLIDE

摘要

A bimodal polymer blend of first and second poly(L-lactide-co-glycolide) copolymers, wherein the molecular weight ratio of the first to the second copolymer is at least about two to one, and the blend has crystallization and hydrolysis rates greater than either of the first or second copolymers alone.
