摘　　要：生物可降解材料——聚丙交酯的合成方法有很多,但是采用"无终止聚合",这一新颖的聚合方法,合成聚丙交酯的研究在最近几年才刚刚开始.此文介绍了一元醇,多元醇,官能化醇作为链转移剂与稀土金属有机配合物组成的"无终止聚合"催化体系对丙交酯开环聚合的最新研究成果,同时介绍了采用这种新聚合方法制备拓扑结构的聚丙交酯及其共聚物.Polylactide is an important part of biodegradable material. Among the numerous synthesis methods ＂immortal polymerization＂ has aroused researchers＇ attention in just recent years. This review introduces the latest developments of lactide ＂immortal polymerization＂ catalytic systems, in which monobasic, polyhydric or functionalized alcohol act as chain transfer agents with rare earth metal as catalysts. This review also presents using ＂immortal polymerization＂ to synthesize polylactide and its copolymer with topological structure.
