ABSTRACT OF THE DISCLOSURE A process for polymerizing an .alpha.-olefin comprising contacting the olefin in liquid phase at a temperature of about 120 to 320°C with a catalyst comprising a component (A) and an organometal component (B), the component (A) being produced by reacting a hydrocarbon-soluble organo- magnesium component (i) of the formula, Image wherein .alpha., p, q, r, s and t each independently is 0 or a number greater than 0. p + q + r + s = m.alpha. + 2 O ? (r + s)/(.alpha. + 1) < 2, m is the valence of M, M is a metal of the 1st to 3rd groups of the Periodic Table, R1 and R2 each independently is a hydrocarbon group having 1 to 20 carbon atoms, X1 and X2 each independently is a hydrogen atom or an organic electronegative group containing 0, N or S, D is an electron donor, with an aluminum compound (ii) of the formula, Image wherein X3 is OR3, OSiR4R5R6, NR7R8 or SR9 wherein R3 and R9 each independently is a hydrocarbon group having 1 to 20 carbon atoms and R4, R5, R6, R7 and R8 each independently is a hydrogen atom or a hydrocarbon group having 1 to 20 carbon atoms, Y is a halogen atom, x and y each independently is a number greater than 0 and less than 3, x + y = 3, and contacting the product of (i) + (ii) with (iii) a compound of titanium and/or a compound of vanadium at a concentration of titanium plus vanadium of at most about 2 mols per liter of the inert reaction solvent, the atomic ratio of Mg/(Ti + V) in (A) being about 3 to about 500.
