摘　　要：针对回收聚对苯二甲酸乙二酯(r-PET)存在的结晶速度慢、成型周期长、冲击性能差等缺陷,综述了采用弹性体、合金化、核壳聚合物、工程塑料、扩链剂等方法增韧改性r-PET的研究进展。r-PET增韧改性的研究方向是实现r-PET的强韧化。According to dominant drawbacks such as low crystallization rate, long processing time and poor notched impact strength of recycled poly（ethylene terephthalate）（r-PET ）, the research progress on the methods for toughening modification of r-PET including elastomer toughening, alloying toughening, core-shell structure polymer toughening, engineering plastics toughening and chain extender toughening was reviewed. The toughening modification research trend of r-PET is toughening r-PET with higher strength.
