Abstract

FIELD: catalysts for olefin polymerization processes. SUBSTANCE: to simplify procedure, catalyst mass is supplemented by silica gel in amount 63.8 to 70.3 wt % in the stage of interaction of magnesium with butyl chloride and iodine in hydrocarbon (hexane) medium followed by adding titanium tetrachloride. Thus magnesium-containing component dissolving operation and those of mixing it with silica gel, and removing solvent through vacuum stripping are eliminated. EFFECT: simplified process. 2 tbl
