随着国家减塑令的发布, 开发聚乳酸(PLA)等生物可降解材料逐渐成为热门话题. 对合成聚乳酸的不同方法进行了讨论. 丙交酯开环聚合法已成为获得高分子量聚乳酸的最常用方法. 因此, 重点介绍了用于丙交酯开环聚合的催化剂设计, 并阐述了聚合的机理, 希望能为设计开发低毒性、高选择性的催化体系指明方向.

关键词: 减塑令, 聚乳酸, 生物可降解, 催化剂, 聚合

With the national plastic reduction order issued, the development of biodegradable materials such as poly(lactic acid) (PLA) has gradually become a hot topic. The different methods for synthesizing polylactic acid are discussed. Since the ring-opening polymerization of lactide has become the major method for preparing PLA, we focused on the catalyst design for the process, and clarified the related mechanisms. This short review may point out the direction for the design and development of low-toxicity and high-selectivity catalyst systems for application.

Key words: plastic reduction order, polylactic acid, biodegradable, catalysts, polymerization
