摘要

为了研究回收PET对PP流变行为的影响，用双螺杆挤出机制备了PP/回收PET和增容PP/回收PET共混物，研究了回收PET用量、不同相容剂对PP/回收PET共混物的动态流变行为的影响。结果表明，PP/回收PET共混物的复数黏度随回收PET含量增加而降低，具有明显的剪切变稀特性。PPgMA提高回收PET复数黏度，但PPgGMA降低共混物的复数黏度，表明回收PET与PPgMA的化学作用较PPgGMA强。PPgMA提高PP/回收PET共混物的动态弹性模量，但PPgGMA使共混物的动态弹性模量和动态黏性模量降低。PPgMA加入使PP/回收PET共混物tan δ降低，但PPgMA用量过高，tan δ反而提高；PPgGMA使共混物的tan δ提高，归结于相容剂的增容和增塑作用。

Abstract

In order to investigate the effect of recycled PET(rPET) on the dynamic rheological behaviour of PP

blends of PP/rPET and compatibilized blends were prepared on a twinscrew extruder. Effects of compatibilizers and rPET contents on the dynamic rheological behaviour of PP blends were investigated. The results showed that the complex viscosity of PP/rPET blends decreased with increasing the content of rPET. Addition of PPgMA increases the complex viscosity of PET. However

addition of PPgGMA decreased the complex viscosity of PET. It indicated that chemical interaction of rPET with PPgMA was higher than that with PPgGMA. Addition of PPgMA increased the dynamic elastic modulus of PP/rPET blends. However

addition of PPgGMA decreased the dynamic elastic modulus and dynamic viscous modulus of PP/rPET blends. Addition of PPgMA decreased the mechanical loss of PP/rPET blends. However

the mechanical loss of PP/rPET blends increased at high content of PPgMA. Addition of PPgGMA increased the mechanical loss of PP/rPET blends. It was explained by the plasticization and compatibilization of PPgMA
