Claim:
1. A method for producing a solid catalyst component for olefin polymerization, the method comprising: bringing one or more magnesium compounds selected from the group consisting of a dialkoxymagnesium, a magnesium dihalide and an alkoxymagnesium halide, a tetravalent titanium halide compound, and one or more first internal electron donor compounds which are aromatic dicarboxylic diesters of formula (I) into contact with each other to effect a reaction, followed by washing, thereby obtaining a first product; bringing a tetravalent titanium halide compound and one or more second internal electron donor compounds into contact with the first product to effect a reaction, followed by washing, thereby obtaining a second product; and bringing one or more third internal electron donor compounds into contact with the second product in the absence of additional tetravalent titanium halide compound to effect a reaction, wherein R R and j is a number of 0, 1, or 2.
