| Abstract | A catalyst composition comprising: (i) a complex comprised of V2X3(ED)m and AlCl2R2 wherein X = Cl, Br, or I, or mixtures thereof ED = an electron donor, which is an ether, a phosphine, a ketone, an isocyanide, or an ester, said electron donor having 2 to 20 carbon atoms R = an alkyl having up to 14 carbon atoms m = an integer from 3 to 6, said complex impregnated into an inorganic oxide support; (ii) sufficient trialkylaluminum compound adsorbed on the inorganic oxide support to provide a molar ratio of adsorbed trialkylaluminum compound to vanadium of about 2.5:1 to about 10:1; (iii) a halocarbon promoter; and (iv) a hydrocarbyl aluminum cocatalyst.
