ABSTRACT:
A solid catalyst component prepared by washing a solid substance, which has been obtained by reacting diethoxymagnesium (a) suspended in an alkylbenzene (b) with titanium tetrachloride (c) in an amount less than 1/2 of the alkylbenzene (b) in a ratio by volume and a phthalic diester (d) at a temperature within the range of 80.degree.-135.degree. C., with an alkylbenzene, and thereafter reacting the solid substance in a presence of an alkylbenzene (b) with titanium tetrachloride (c) in an amount less than 1/2 of the alkylbenzene (b) in a ratio by volume as well as an olefin polymerization catalyst comprising (A) the solid catalyst component specified above, (B) a silicon compound of the general formula:
