PP复合成核剂的研究进展

Advances in research and development of complex nucleating agent for PP

综述了用于丙烯聚合的α成核剂(山梨醇衍生物类、有机磷酸盐类、松香类等)和β成核剂复合化的研究进展。成核剂的复合化主要是现有成核剂通过化学改性实现多功能化、不同成核剂之间的相互协同以及成核剂与其他助剂的协同。

This paper reviewed the advances in studies on compounding of the complex transparent nucleating agents for polypropylene（PP）, including α-type nucleating agents （such as sorbitol derivatives, organic phosphates and rosin acid and its salts） and β-type nucleating agents. Compounding of nucleating agents is considered as an important tendency in this field and is usually carried out via chemical modification of the existing nucleating agents in order to realize muhi-functionalization, synergism between diverse nucleating agents and synergism between nucleating agents and other auxiliary agents.
