FIELD: chemistry.
SUBSTANCE: invention relates to catalyst systems which contain both a metallocene catalyst component and a Ziegler—Natta type catalyst component. Described is a catalyst composition for olefin polymerisation, comprising: (A) a supported catalyst comprising: (a) fluorinated aluminum oxide with a silicon dioxide coating; (b) a magnesium compound and (c) titanium (IV) or vanadium; (B) a metallocene compound and (C) a cocatalyst, where the magnesium compound contains a magnesium halide or magnesium alkoxide and the cocatalyst is an organoaluminium compound containing trimethylaluminium, triethylaluminium, tri-n-propylaluminium, tri-n-butylaluminium, triisobutylaluminium, tri-n-hexylaluminium, tri-n-octylaluminium or any combination thereof.
EFFECT: technical result is creation of new catalytic compositions with high catalytic activity.
