摘要
综述了二酰胺β晶型聚丙烯(PP)成核剂的制备方法及其成核机理,全面评述了二酰胺成核剂在均聚PP、共聚PP、PP与其他聚合物共混体系中的应用,介绍了二酰胺成核剂与α成核剂、有机过氧化物的复合应用进展。最后指出应重点加强二酰胺成核剂结构与成核性能关系、成核机理及与其他助剂复合规律的研究。
Preparation methods and their nucleating mechanism for diamideβform nucleating agents were described in detail.Application situation of the kind ofβnucleating agents especially in different homopolymer PP,copolymer PP and PP blend with other polymers was summarized comprehensively and the application effects of diamideβnucleating agents mixed with a form nucleating agent or organic peroxides were reviewed.At last it is suggested that the study on the relation of the structure of diamide nucleating agents and properties, nucleation mechanisms and combination rules with other additives should be strengthen.
