ABSTRACT:
A catalytic component for polymerization of an .alpha.-olefin is prepared by allowing an organo-magnesium compound expressed by the generic formula of RMgX (wherein R represents a hydrocarbon group having 1 to 20 carbon atoms and X a halogen atom or a hydrocarbon group having 1 to 20 carbon atoms) to react with carbon tetrahalide in the presence of an electron donor compound to obtain a solid product; by treating the solid product with phenols at 90.degree. to 180.degree. C.; and by further treating the phenol treated solid with a halogenated titanium compound. Homo- or co-polymerization of an .alpha.-olefin is carried out in the presence of a catalyst composition consisting of the catalytic component thus prepared and an organo-aluminum compound.
