摘要: 综述了聚乳酸共聚增韧改性的研究进展,详细介绍了直接缩聚法、开环聚合法、扩链剂法等聚乳酸的共聚改性方法,其中直接缩聚法得到的聚合物的相对分子质量较低,开环聚合法得到的聚合物的相对分子质量较高,扩链剂可以与其他2种方法配合使用。最后,综述了聚乳酸共聚物在医学领域及包装领域的应用研究进展。

Abstract: This review focused on the recent research progress in the modification of poly(lactic acid). The modification methods included direct polycondensation method, ring-opening polymerization, and chain-extending method. The molecular weight of poly(lactic acid) copolymers obtained by ring-opening polymerization was higher than that by direct polycondensation method. The chain-extending method could be used together with others. The application of modified poly(lactic acid) was reviewed, particularly in medical and packaging area.

Key words: packaging material, poly(lactic acid), copolymerization, modification
