摘要
综述了近年来烯烃聚合用的非茂单中心催化剂 (包括非茂体系催化剂和后过渡金属催化剂 )的结构特点、技术现状及最新进展情况。采用非茂单中心催化剂生产的树脂相对分子质量分布较窄 ,综合了采用Z -N催化剂和茂金属催化剂的优点 。
The structure characteristic,technology status and development of non-metallocene single site catalysts,including post-transition metal catalysts and non-metallocene catalysts,used in the olefin polymerization were reviewed.This kind of catalysts had many advantages and low cost.
