ABSTRACT:
A vanadium catalyst component for the polymerization of 1-olefins and a process for making said catalyst component are disclosed. The catalyst component is prepared by fluoriding a support comprising silica. Use of the catalyst component provides a catalyst with increased activity, increased response to hydrogen for chain termination, increased response to comonomer for resin density reduction, and allows the molecular weight distribution of the polymers to be independently controlled by controlling the amount of fluorination and the fluorination temperature.
