携带叠氮和氨侧基的脂肪族聚酯的合成和表征

通过丙交酯(LA)与环状碳酸酯单体共聚的方法制备了一种侧链带有溴原子的脂肪族聚酯, 并将溴原子用叠氮基团取代, 通过Cu(Ⅰ)催化的Click反应将其氨基化, 得到了侧链带有氨基的脂肪族聚酯.

Synthesis and Characterization of Azido-and Amino-bearing Aliphatic Polyesters

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.
