ABSTRACT OF THE DISCLOSURE A catalyst useful for polymerizing olefins which comprises a solid catalyst component [A] and an organometallic component [B], the solid catalyst component [A] being obtained by reacting (1) a solid inorganic oxide, (2) a hydrocarbon-soluble organomagnesium component of the general formula M.alpha.Mg.beta.R?R?XrYs wherein .alpha., p, q, r and s each independently is 0 or a number greater than 0, .beta. is a number greater than 0, p + q + r + s = m.alpha. + 2.beta., m is the valence of M, M is a metal of the 1st and 3rd groups of the Periodic Table. R1 and R2 each independently is a hydrocarbon group having 1 to 20 carbon atoms, X and Y each independently is an OR3, OSiR4R5R6. NR7R? or 5R9 group wherein R3, R4, R5, R6, R7 and R9 each independently is a hydrogen atom or a hydrocarbon group having 1 to 20 carbon atoms and R9 is a hydrocarbon group having 1 to 20 carbon atoms, or of the reaction produc? of M.alpha.Mg.beta.R?R?XrYs with at least one electron donor selected from the group consisting of ethers, thoiethers, ketones, aldehydes, carboxylic acids or derivatives thereof, alcohols, thioalcohols and amines and (3) a chlorosilane compound having a Si-H bond and of the formula HaSiC?bR??(a+b) wherein R10 is a hydrocarbon group having 1 to 20 carbon atoms, 0 < a ? 2 b > 0 and a + b ? 4, separating a reaction product from the reaction mixture and washing the separated reaction product with an inert hydrocarbon and reacting the washed reaction product with (4) a titanium compound having at least one halogen atom and/or a vanadium compound having at least one halogen atom, and a polymerization process employing such a catalyst.
