摘　　要：综述了有机类成核剂的主要类型(山梨醇类、松香酸皂类、有机磷酸盐类、磷酸金属盐类)和结构特征,阐述了有机类成核剂对聚丙烯(PP)性能的影响及其在PP结晶、成核过程中的作用。结果表明,成核剂能使PP晶粒细微化、结晶度增加,使PP的热变形温度、透明度、刚性、冲击强度等性能提高。The main types and structural characteristics of the organic nucleating a gents （sorbitol, rosin acid soap, organic phosphates, phosphoric acid metal salts） were described. The effects of the organic nucleating agent on the properties of polypropylene （PP） and the role of crystallization on the nucleation process for PP were discussed. The results show that the nucleation agent can induce the PP grain refinement and increase the crystallization d ty, impact strength egree of PP. The heat deformation temperature, transparency, rigidi and other properties of PP are improved.
