ABSTRACT:
A process for producing a trivalent titanium compound-containing solid catalyst for use in the polymerization of olefins which comprises treating, with an ester compound, a solid product obtained by reducing a titanium compound represented by the following general formula: ##STR1## (R.sup.1 represents hydrocarbon group having 1 to 20 carbon atoms, X represents halogen atom, and n represents a number satisfying 0<n.ltoreq.4) with an organomagnesium compound in the presence of an organic silicon compound having Si--O bond, and thereafter treating it with a mixture of an ester compound and titanium tetrachloride.
