摘　　要：在75 kg/h聚丙烯中试装置中对高流动高模量抗冲聚丙烯进行开发研究,从催化剂的选择、氢调性、外给电子体的选择、乙烯质量分数、成核剂的影响等方面进行实验,开发出熔融指数为30、弯曲模量达到1 600 MPa、简支梁冲击强度(常温)为6.5 k J/m^2的高流动性刚韧平衡聚丙烯产品。The high fluidity and high modulus impact polypropylene product was studied in the 75 kg/h pilot plant. Experiments were conducted on the effects of polypropylene catalyst, hydrogen sensitivity, election of external electron donor, mole fraction of ethylene and nucleating agents. The high fluidity and rigid - tough balance polypropylene products with melt flow rate of 30, flexural modulus of 1 600 MPa, and Charpy impact strength of 6.5 kJ/m^2（ normal temperature） polypropylene were successfully developed.
