摘要 聚乳酸(PLA)具有优异的生物可降解性、可吸收性、良好的力学性能和可塑性,但也存在脆性大、冲击强度较低等缺陷。通过共聚增韧改性的方式能够有效地改善上述缺陷,扩大其应用范围。综述了PLA共聚增韧的主要方法及研究发展现状,主要包括嵌段共聚、接枝共聚和交联增韧3种方法。介绍了改性后聚乳酸的在医学和包装工业上的应用。对未来聚乳酸共聚增韧发展方向作出展望,开发绿色化的合成工艺、降低生产成本、提高聚合物稳定性、寻找更合适的改性单体是研究重点。

Abstract: Polylactic acid(PLA)has fine biodegradable,bioabsorbable and fine mechanical properties,but it is brittle and has poor pliability.Thus,it has to be modified to enhance its pliability to expand its scope of application via the way of copolymerization.The main methods and recent research progress of toughening modification of PLA by copolymerization were reviewed,including the block copolymerization,grafting copolymerization and crosslinking toughening.The application of modified PLA in medicine and packaging industry was also introduced.In the future,it should focus on that the development of green chemical synthesis,reduced the production cost,improved the stability of the polymer and found a more suitable monomer.
Key words:  polylactic acid (PLA)    copolymerization modification    toughening
