In the present study, the dynamic viscoelastic properties for binary blends consisting of polypropylene (PP) and poly (ethylene-1-octene) (POE) were investigated using a Stresstech Rheometer in molten states at 210 °C. The results show that the blends with different content of POE present diversified rheological behaviors. Meanwhile, the blends with 10 wt% and 20 wt% POE show especial rheological behaviors. The dynamic complex viscosity of the blends with 10 wt% and 20 wt% POE are higher than that of others. The storage modulus and loss modulus of the blends with 10–40 wt% POE are different from other blends, and the blends with 10 wt% POE present the largest relaxation time. This behavior is probably related to the miscibility and long chain branch of POE in the PP/POE blends.
