Functionalized aliphatic polyesters, especially those with pendent hydroxyl, carboxyl and amino groups, have attracted much research interest in recent years due to their perfect biocompatibility, biodegra-dability and reactivity. Copolymerization of lactide with functionalized cyclic carbonate monomers proved to be an efficient way to functionalize aliphatic polyesters. However, random co-polyesters with pendent amino groups were seldom reported. This article reported a facile way to prepare aliphatic polyesters with random pendant azido and amino groups via Click reaction.
