ABSTRACT:
A method for the production of a catalyst component for use in the polymerization of an olefin, which method comprises causing a magnesium-containing solid obtained by contact of (A) magnesium metal, (B) a halogenated hydrocarbon represented by the general formula, RX, wherein R stands for an alkyl, aryl, or cycloalkyl group having 1 to 20 carbon atoms and X for a halogen atom, and (C) a compound of the general formula, X.sub.n.sup.1 M(OR.sup.1).sub.m-n, wherein X.sup.1 stands for a hydrogen atom, a halogen atom, or a hydrocarbon group having 1 to 20 carbon atoms, M for a boron, carbon, silicon, aluminum, or phosphorus atom, R.sup.1 for a hydrocarbon group having 1 to 20 carbon atoms, and m for the valency of said atom M, providing that m>n.gtoreq.0 is satisfied, to contact (D) a halogen-containing alcohol and then contact (E) a titanium compound.
