The present invention relates to a catalyst system for olefin polymerization and to a process for olefin polymerization. More particularly, the invention relates to a catalyst system for the preparation of ethylene-propylene-copolymers, optionally containing one or more diolefins, under slurry polymerization conditions using a vanadium-based catalyst system which contains a halogenated compound which acts as a catalyst activator.
