ABSTRACT:
A catalyst useful in the polymerization of olefins, especially ethylene, is disclosed. The catalyst is obtained by admixing a zinc composition, a zirconium composition and a vanadium composition. The catalyst may be combined with a co-catalyst and, optionally, a modifier to yield an olefin polymerization system. The catalyst exhibits extremely high activity, good hydrogen response and produces polymers having broad molecular weight distribution ("MWD") and manifesting bimodal MWD profile.
