Abstract
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. (R1)kC6H4-k(COOR2)(COOR3) (1)R4R5C(COOR6)2 (2) A polymer that exhibits high activity with respect to hydrogen, high stereoregularity, and high bulk density can be obtained using a catalyst including a solid catalyst component obtained by the method.
