摘　　要：分析了控制高流动、高抗冲聚丙烯的等规指数对其产品物理与机械性能的影响,并考察了等规指数与聚合温度、反应时间、乙丙橡胶含量等的关系。研究得出,在生产高流动、高抗冲聚丙烯时,均聚物母体的等规指数应不低于97%,乙丙共聚产品的等规指数应不低于85%。This paper analyzed the influence of controlling isotactic index of high flow and high impact polypropylene （PP） on physical and mechanical properties of the PP product, and explored the dependence of isotactic index on polymerization temperature, reaction time and ethylene-propylene rubber content. The study showed that when producing high flow and high impact PP, the isotactic index of the pre-homopolymer and the ethylene-propylene copolymer was required not to be lower than 97% and 85%, respectively.
