摘　　要：探讨一种经济有效并且能实现规模化生产的提高共聚聚丙烯(PP)冲击韧性的新方法;简述生产控制过程;介绍了β成核剂在共聚聚丙烯冲击改性中的机理和效果;在保持基础树脂屈服拉伸强度等优良刚性指标的同时,提高了PP的冲击强度。A new method is discassed, which is cost effect and has put into large scale production that can improve co-poly PP impact strength. The production process is briefed. The mechanism and effect of β-nucleates on modifying co-polypropylene are introduced which improve PP impact strength as well as retain the base resin superior toughness targets：yield strength and tensile strength, etc.
