| Abstract: | The thermal stability of polypropylene EPS30R from Qilu Petrochemical Company, was evaluated through measuring the curve of torque versus time and response time and observing the variation in color of the resin under the extrusion processing conditions dynamically simulated by HAAKE torque rheometer RH600 mixer at high temperature and constant shear force. Stability of the polypropylene products prepared with different recipe was compared with the purpose of testing the efficiency of the antioxidants inside the resins. |
