摘　　要：聚丙交酯(或聚乳酸)是一种可降解的塑料,符合环境友好的要求,而稀土金属配合物在催化丙交酯开环聚合方面具有活性高、反应条件温和、副反应少、残余催化剂无毒害等优势。文章从专利文献和非专利文献两方面分别进行了梳理,并从稀土金属配合物本身的特点出发分析了其产业化中存在的问题以及可能的解决途径。Polyactide(PLA)is currently attracting interest as a biodegradable thermoplastic derived from carbon-neutral"biomass feedstcoks.The advantages of rare earth catalysts for the ring-opening polymerization of lactides are emphasized such as high activity,mild conditions.The article analyzes the application of rare earth metal in ring-openning polymerization of polycactides in related patents and nonpantents in recent years,and summarizes and analyzes the key patented technologies in recent years,which can provide info rmation for subsequent researchers.
