ABSTRACT:
A Ziegler type supported catalytic component for polymerization of an .alpha.-olefin is prepared by allowing an organo-magnesium compound expressed by a generic formula of R'MgX' (wherein R' represents a hydrocarbon group having 1 to 20 carbon atoms and X' either a halogen atom chosen out of chlorine, bromine and iodine or a hydrocarbon group having 1 to 20 carbon atoms) to react wtih carbon tetrahalide in the presence of an electron donor compound to obtain a solid product through a solid-liquid separation process; by heat treating the separated solid product with a carbon halide; by treating the heat treated solid product with phenols at 90.degree. to 180.degree. C.; and by treating this phenol treated product further with a halogenated titanium compound. Homo- or co-polymerization of an .alpha.-olefin is carried out in the presence or a catalyst composition consisting of the above catalytic component and an organo-aluminum compound. With this catalytic component, stereospecific polymerization of an .alpha.-olefin can be stably carried out at high temperature.
