Combination of ring-opening polymerization and'click'chemistry towards functionalization of aliphatic polyesters

摘要

Azide pendent groups of aliphatic polyesters have been derivatized into tertiary amines,ammonium salts and poly-(ethylene oxide)grafts.The experimental conditions have been optimized(organic solvent,35 deg C),such that the aliphatic polyesters are not degraded,including even poly(lactide)which is very sensitive to attack by weak nucleophiles.
