摘　　要：聚乳酸是一种完全生物降解的热塑性线性脂肪族聚酯,具有较好的力学性能,但是性能刚而脆,大大限制了其应用。详细介绍了国外聚乳酸共混增韧的研究进展。The polylactide was a kind of thermoplastic linear aliphatic polyester, which biodegrade fully in environment, and had a very excellent mechanical properties. However, the rigid and brittle properties considerably limited its application. It was introduced in detail that the abroad progress on polylactide toughened by blending method.
