FIELD: catalysts for olefin polymerization processes. SUBSTANCE: method including preparing suspension containing "aerosil" and silicon dioxide hydrosol, drying suspension at 100-200 C to form powdered silica gel, covering it with chromic anhydride from aqueous solution, and activating catalyst mass at 400-600 C is distinguished by that chromic anhydride is applied by way of introducing its aqueous solution in suspension preparation stage followed by performing spray drying. EFFECT: simplified process and increased catalyst activity.
