ABSTRACT:
An .alpha.-olefin polymerizing catalytic component is obtained by treating, with alcohol and/or phenol, a solid product obtained by allowing an organo-magnesium compound expressed by a generic formula of R'MgX' (wherein R' represents a hydro-carbon group having 1 to 20 carbon atoms and X' a halogen atom selected from the group consisting of chlorine, bromine and iodine or a hydrocarbon group having 1 to 20 carbon atoms) to react with a halogenating agent in the presence of an electron donor; by treating the treated matter with a halogen-containing titanium compound, either after heating under reduced pressure or without such heating; and by treating the product further with a mixture or a complex consisting of an organo-aluminum compound, an organic acid ester and a poly-siloxane. Homo- or co-polymerization of an .alpha.-olefin is carried out in the presence of a catalyst system comprising the catalytic component and an organo-aluminum compound.
