摘　　要：概述了可降解塑料PBS(聚丁二酸丁二醇酯)的两种扩链方法。按照扩链剂与PBS端基的反应特点,将PBS用扩链剂分为适于端羟基的扩链剂和适于端羧基的扩链剂两种。介绍各类扩链剂的研究进展及优缺点,同时概述各自的反应机理,提出进一步开发PBS用扩链剂的发展方向。The two chain-extending methods of degradability plastic poly （ butylenes sueeinate） （PBS） are summarized. Accoding to the react character of chain-extenders and the end groups of PBS,the chain-extenders of degradability PBS will be devided into two categories ：the chain-extenders of applicable to hydroxyl-terminated PBS and applicable to carboxyl end group of PBS. The research progress,advantages and disadvantages of all kinds of chain extenders are also introduced. Furthermore, the reaction mechanism of all kinds of chain-extending reactions are summarized, and the development of chain-extenders in the future are also pointed out.
