聚丙烯β成核剂的研究进展

摘要

对近年来聚丙烯(PP)β 成核剂的研究进展进行了综述,首先论述了PP的 β 晶型及 β 成核剂的成核机理,然后详细介绍了不同种类 β 成核剂的研究进展情况.同时,针对现阶段 β 成核剂研究和开发过程中存在的问题提出意见和建议,并对聚丙烯 β 成核剂的未来发展作出展望.%The research progress of β nucleating agent for polypropylene (PP) in recent years was reviewed. Firstly,the βcrystal form of PP and nucleation mechanism of β nucleating agent were expounded,then,the research advances of different kinds of β nucleating agents were introduced detailedly. Meanwhile,opinions and suggestions on the problems which existed in the re-search and development of βnucleating agents at present stage were put forward. Finally,the future development of β nucleating agent for PP was forecasted.
