ABSTRACT:
A catalytic component for polymerization of an .alpha.-olefin is prepared through a process wherein a solid product obtained by allowing an organo-magnesium compound or a mixture of an organo-magnesium compound and an organo-aluminum compound or their reaction product to react, in the presence of an electron donor and an .alpha.-olefin, with a mixture of a halogenating agent other than a halogenated titanium compound and a titanium compound or their reaction product is treated with an alcohol and/or a phenol. The treated product may be further treated 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 and an organo-aluminum compound or with a concomitant electron donor used together with the catalyst composition.
