摘　　要：据统计,全球每年产生2.5亿吨废旧塑料。塑料在使用过程中,受到多重环境因素(如光、热、氧、微生物等)的影响而老化,导致其性能恶化,难以直接利用。改性是实现废旧塑料有效利用的重要方法。本文介绍了废旧塑料的常见改性方法,特别是反应挤出在废旧塑料改性利用中的应用。250 million tons of waste plastics were discarded every year in the world.There were plenty of hardships to recycle waste plastics due to the degradation in consequence of multiple factors in the using process (such as light,heat,oxygen,microorganisms,etc.).Modification was an important method to achieve effective recycling of waste plastics.In this paper,we introduced some methods,especially the applications of reactive extrusion in the modification of waste plastics.
