PET/PPS blends were prepared by extrusion compounding PPS with high viscosity PET.The influence of PPS on the mechanical properties and rheological behaviors of the blends were studied.The results showed that the tensile strength and flexural strength of the PET were improved by adding of PPS,while the notched impact strength of it was slightly decreased.With the increase of PPS,the rheological behavior of the blends exhibited a pseudoplastic characteristic,and the non-newtonian index n increased initially and then decreased,but the viscous flow activation energy of the blends system decreased continuously.The optimum comprehensive properties and processing condition were achieved at 5 mass fraction of PPS addition.
