β晶型成核剂的合成研发进展

The Research and Development of the β-form Nucleating Agent

综述了国内外聚丙烯β晶型成核剂合成方法的研发进展,比较了不同晶型成核剂的性能。目前主要的β晶型成核剂商品多为含亚酰胺键的化合物。

The β form nucleating agent is a plastics additive which can increase β form crystal content in PP. The impact strength and heat distortion temperature are raised with the inceasing of β-form crystal nucleating agent in PP. The research and development of β-form nucleating agent＇s synthesis at home and abroad were reiewed. The main commodities of β form nucleating agents are the compounds which has amid links in its molecular.
