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 stands 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 stands for a boron, carbon, aluminum, silicon, or phosphorus atom, R.sup.1 stands for a hydrocarbon group having 1 to 20 carbon atoms, and m stands 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) an electron donor type compound and (F) a titanium compound.
