ABSTRACT:
A catalyst system is provided comprising a titanium catalyst component produced by contacting a benzenediazonium tetrafluoroborate with a titanium tetrahalide such as titanium tetrachloride and a cocatalyst. Preferred cocatalysts are organoaluminum compounds. The catalyst system of this invention is broadly suitable for this polymerization of 1-olefins and is particularly suited for the production of high molecular weight ethylene polymers.
