FIELD: chemistry.
SUBSTANCE: invention relates to a method for producing a catalyst for the polymerization of olefins and a process for the polymerization of olefins. Method for producing a catalyst for the polymerization of olefins is carried out by contacting metallic magnesium with an organic halide RX, in which R is an organic group containing from 5 to 20 carbon atoms, X is a halogen atom, to form soluble product (I), followed by adding to product (I) a silicon compound containing an alkoxy group or an aryloxy group, to form solid product (II), and subsequent treatment of product (II) with tetrachloride titanium and an electron donor compound, metallic magnesium is contacted with organic halide RX in the presence of an aromatic hydrocarbon containing from 6 to 10 hydrocarbon atoms.
EFFECT: proposed method allows producing a catalyst with indicators of activity and morphology that are non-inferior to the known sample, and reducing the amount of harmful chlorine-containing organic waste to a minimum, which allows eliminating the stage of discharge and utilization thereof.
