ABSTRACT:
A catalyst system is disclosed as a combination of at least two components comprising: component A which is one or more titanium compounds and one or more vanadium compounds mixed with one or more organoaluminum compounds in such in amount that the atomic ratio of aluminum to the sum of titanium and vanadium is at least 3; and component B which comprises one or more organoaluminum compounds,
wherein one or both of components A and B contain a chloride, and wherein during use such two components are fed, separately or in combination, directly to the reaction vessel in such an amount that the atomic ratio of the chlorine from components A and/or B to the sum of titatium and vanadium of component A is at least 6. The catalyst system is suitable for copolymerizing ethylene and optionally minor amounts of 1-alkenes and/or dienes at high polymerization temperatures.
