Poly(L-lactide-co-glycolide) (PLGA) is a biodegradable and biocompatible copolymer synthesized from the ring opening polymerization of lactide and glycolide. Due to the ester linkages found in the polymer backbone, these polymers are able to degrade via hydrolysis. Depending on the ratio of monomers used and polymer block structure, different forms of PLGA can be obtained. These differing forms yield materials with different degrees of crystallinity, thermal transitions, solubility, and rates of degradation. Synonyms: PLGA. Product ID: MSMN-031.
