限定几何构型催化剂的研究进展

The Research Achievement and Development of Constrained Geometry Catalyst Technology(CGCT)on Polyolefins

简单介绍了限定几何构型催化剂的合成 ,催化剂结构与催化烯烃聚合活性的关系 ,该系列催化剂在聚合过程中的特征 ,以及该催化剂在目前的几个典型的发展方向。

In this paper,the research achievment and development of Constrained Geometry Catalyst Technology(CGCT)on polyolefins were reviewed.Several methods of synthesis on CGCT catalysts were introduced.The relationships berween structures and activities of the family of CGCT catalysts which gives rise to long chain branch polymers were discussed.Dual functional catalysts for ethylene polymerization and functional polymers were made by CGCT.
