| 摘 要： | 聚乳酸是目前最具竞争力的生物降解高分子材料,但也存在脆性过大、亲水性差、售价太高等明显缺点。本文综述了近年来以聚乳酸为主链进行的接枝聚合反应。聚乳酸接枝物的合成,能够明显改善聚乳酸的表面性能。而且可以在聚乳酸与其他高分子材料的共混体系中发挥明显的增容作用,为新型聚乳酸共混物的制备提供了可能性。

| Abstract: | Polylactic acid(PLA) was the most competitive biodegradable polymer.It had some obvious drawbacks such as higher brittleness,bad hydrophilicity and high price.The latest research developments of the graft copolymerization of polylactic acid main chain were reviewed.The graft copolymer can improve the surface properties of PLA and serve as compatibilizer in PLA blend.The graft copolymer can help to produce new PLA blend. |
