摘　　要：通过对r-PET进行改性,可以达到改善材料性能的目的,这不但可以减少环境污染,而且还可以节省资源。从增黏改性、固相挤出法改性、共混改性、反应改性和增容改性等几个方面论述了聚对苯二甲酸乙二醇酯(PET)瓶回收料改性技术的研究进展。Melioration material performance can be obtained by modification of the reeyded PEr bottles （r- PEr）, which can not only decrease environment pollution but also save resource. The research development of r- PEr modification technique was summarized from five aspects： increase viscidity modification, solid- state extrusion modification, simple mixing modification, reactive modification, and modification by adding compotibilizer.
