| Abstract: | The polypropylene with melt flow rate of 30~36 g/10 min increased from 9-11 g/10 min,flexural modulus over 900 MPa,tensile strength at yield of above 18 MPa and impact strength higher than 14 kJ/m2 was prepared through stabilizing quality of the degradable base resin powder and augmenting the peroxide content.The requirements for pelleting of the polypropylene having high melt flow rate were satisfied by properly adjusting the parameters of the extruder. |
