FIELD: copolymerization of alpha-olefins. SUBSTANCE: alpha-olefins are subjected for copolymerization in the medium of hydrocarbon solvent in the presence of catalyst. Catalyst is made by interaction in the medium of solvent of the following components: compound of the general formula LlMX2, where L - cyclopentadienyl, 2- (η5-cyclopentadienyl)-2-(η5-fluorenyl)-propane or (tert. -butylamido)-dimethyl(tetramethyl-η5-cyclopentadienyl) silane; X - benzyl or methyl; l = 1 or 2; M - titanium or zirconium, and tetra(pentafluorophenyl) borate at molar ratio from 1: 1 to 1: 1.3. EFFECT: improved method of catalyst preparing. 4 cl
