PROCATALYST FOR POLYMERIZATION OF OLEFINS

摘要

The invention relates to a procatalyst for polymerization of olefins. The invention also relates to a process for preparing said procatalyst. Furthermore, the invention is directed to a catalyst system for polymerization of olefins comprising the said procatalyst, a co-catalyst and optionally an external electron donor; a process of preparing polyolefins by contacting an olefin with said catalyst system and to polyolefins obtained or obtainable by said process. The invention also relates to the use of said procatalyst in the polymerization of olefins.
