Beschreibung

General description

Ester terminated Poly(D,L-lactide) (PDLLA, RESOMER^® ) is a copolymer of L and D-lactic acid and (or L and D lactide). The structure is highly irregular and amorphous. RESOMER^® polymers are bioresorbable aliphatic polyesters comprised of a range of different ratios of lactide and glycolide monomers, PLA stereochemistries, and end-group functionalization.
