ABSTRACT A catalyst system that is a combination of at least two com- ponents A and B, which components comprise: A : one or more titanium compounds and one or more vanadium com- pounds, mixed with one or more organoaluminium compounds in such an amount that the atomic ratio of aluminium to the sum of titanium and vanadium is at least 3, B : one or more organoaluminium compounds, one or both of components A and B containing a chloride, and which two components are fed, separately or in combination, direct 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 titanium and vanadium of component A is at least o, is suitable for (co)polymeri- zation of ethylene and optionally minor amounts of 1-alkenes and/or dienes at high polymerization temperatures.
