摘要
本文介绍了以ＩＶ族过渡金属钛、锆、铪为基础的茂金属催化剂的组成、结构、特点、分类及反应机理和助催化剂的发展，综述了茂金属催化剂在聚乙烯中的开发、应用及进展，提出了发展我国茂金属催化剂的建议。
The composition, structure, feature, classification and reaction mechanism of Group IVB(Ti, Zr and Hf) metallocene catalysts and the development of cocatalysts are introduced in this paper. The development and application progress of the metallocene catalysts in polyethylene are surveyed, and suggestions of developping the metallocene earalysts in our country are put forward.
