| 摘 要： | 聚乳酸因具有良好生物相容性、生物降解性、生物可吸收性以及优良的力学性能，在农业、食品包装、医疗卫生等领域得到了广泛应用，但因其玻璃化转变温度较高、性脆、柔韧性差，需通过增韧改性以提高其加工和应用性能。本文综述了聚乳酸通过共聚、交联、共混等改性方法增加柔韧性的最新研究进展。

| Abstract: | Polylactic acid（PLA）is widely used in agriculture，packaging，medicine and health care because it is a biocompatible，biodegradable and bioabsorbable polymer and has fine mechanical property. But it is hard and brittle and has poor pliability because it has a high glass transition temperature. Thus，it has to be modified to enhance its pliability to improve handling and application. In this paper，the recent research progress of toughening modification of PLA via copolymerization，cross-linking，and blending is reviewed. |
