摘要
综述了主流的非桥联型、桥联型、限定几何构型和吡啶氨基型中典型的6个茂金属催化剂在乙烯与α-烯烃高温溶液聚合方面的应用.为了探究桥联型茂金属催化剂微观结构与烯烃聚合活性的内在关系,着重分析了4个茂金属催化剂的几何结构参数,揭示了该类催化剂通过改变配位空间以提高聚合性能的方向.
Abstract
The application of six typical metallocene catalysts for high-temperature solution polymerization of ethylene and α-olefins is reviewed,including mainstream non bridged,bridged,restricted geometry,and pyridine amino types.The geometric structural parameters of four metallocene catalysts were analyzed to explore the intrinsic relationship between the microstructure of bridged metallocene catalysts and the activity of olefin polymerization,which reveals the direction of improvement of polymerization performance of catalysts by changing the coordination space of these catalysts.
