摘要

制备了不同相容剂增容回收PET/PP共混物，用DSC方法研究了相容剂对r-PET结晶与熔融行为的影响，r-PET对PP结晶与熔融行为的影响和相容剂对r-PET/PP共混物结晶与熔融行为的影响，观察到PP结晶温度随着r-PET含量增加而提高，r-PET结晶温度随着PP含量增加而降低，相容剂加入明显降低共混物中r-PET结晶温度，但不同相容剂对共混物中r-PET结晶与熔融行为影响不大，共混物中PP结晶性能与相容剂的大分子链有关。

Abstract

The recycled poly (ethylene terephthalate)/polypropylene (r-PET/PP) blends were prepared with different compatibilizers. The differential scanning calorimetry (DSC) was used to investigate the effect of compatibilizers on crystallization and melting behavior of r-PET

the effect of r-PET on crystallization and melting behavior of PP and the effect of compatibilizers on crystallization and melting behavior of r-PET/PP blends. The results indicated that the crystallization temperatures of PP increased with increasing r-PET contents and the crystallization temperatures of r-PET decreased with increasing PP contents. Addition of compatibilizers significantly decreased the crystallization temperatures of neat r-PET and r-PET component in the blends. However

the different compatibilizers had no influence on the crystallization and melting behavior of blends and the crystallization behavior of PP in the blends depend on the kinds of compatibilizers.
