In order to investigate the effect of recycled PET(rPET) on the dynamic rheological behaviour of PP
blends of PP/rPET and compatibilized blends were prepared on a twinscrew extruder. Effects of compatibilizers and rPET contents on the dynamic rheological behaviour of PP blends were investigated. The results showed that the complex viscosity of PP/rPET blends decreased with increasing the content of rPET. Addition of PPgMA increases the complex viscosity of PET. However
addition of PPgGMA decreased the complex viscosity of PET. It indicated that chemical interaction of rPET with PPgMA was higher than that with PPgGMA. Addition of PPgMA increased the dynamic elastic modulus of PP/rPET blends. However
addition of PPgGMA decreased the dynamic elastic modulus and dynamic viscous modulus of PP/rPET blends. Addition of PPgMA decreased the mechanical loss of PP/rPET blends. However
the mechanical loss of PP/rPET blends increased at high content of PPgMA. Addition of PPgGMA increased the mechanical loss of PP/rPET blends. It was explained by the plasticization and compatibilization of PPgMA
