Abstract

See full text

A method for producing a solid catalyst component for olefin polymerization includes bringing a magnesium compound, a tetravalent titanium halide compound, and an electron donor compound represented by a general formula (1) into contact with each other, reacting the mixture, washing the resulting reaction product to obtain a solid component, bringing the solid component, a tetravalent titanium halide compound, and an electron donor compound represented by a general formula (2) into contact with each other, reacting the mixture, and washing the resulting reaction product.
