摘　　要：综述抗冲共聚聚丙烯刚韧平衡的调节措施,影响其刚韧平衡的主要因素有:键合乙烯量、气相比、二聚物的特性粘数、成核剂、分子量分布以及橡胶相分布等,对每个影响因素都要仔细选择和控制才能得到高质量的多相共聚产品。Overviews adjusting means of rigid - tough balance for impact polypropylene copolymer. The major factors influencing rigid - tough balance of polypropylene include amount of bonded ethylene, ethylene/propylene ratio in gas phase, intrinsic viscosity, nucleating agent, molecular weight distribution and rubbery phase distribution, etc. In order to attain high quality multi - phase polypropylene eopolymer, every influencing factor must be selected and eontroled carefully.
