ABSTRACT:
A solid catalyst component for olefin polymerization catalysts prepared by suspending diethoxymagnesium (a) in an aromatic hydrocarbon (b) which is liquid at normal temperature and bringing the suspension into a first contact with titanium tetrachloride (c) to form a product and bringing it into a second contact with tianium tetrachloride (c) in such manner that a diester (d) of an aromatic dicarboxylic acid and calcium chloride (e) are allowed to coexist at any stage of the above suspending and/or contacts, the calcium chloride (e) being used in an amount of 1-2 grams per gram of the diethoxymagnesium (a). This solid catalyst component exhibits, when applied to the polymerization of olefins, a surprisingly enhanced polymerization activity per titanium atom and a high stereospecific performance and scarcely necessitates any deashing treatment, thus affording a great economical advantage.
