摘　　要：综述了结晶对聚丙烯性能的影响、成核剂的种类及其在聚丙烯结晶过程中的作用。成核剂使聚丙烯结晶细微化、结晶度增加 ,聚丙烯的热变形温度、透明度、冲击强度等性能提高 。The influence of the crystallization on PP's properties and the effect of the nucleating agents in the process of crystallization are discussed. The nucleating agents miniaturize the crystallite and increase the crystallinity. They also improve PP's molding characteristics and its properties such as thermal deformation temperature, transparency and notch impact strength.
