Olefin polymers with a broad molecular weight distribution can be obtained while maintaining the high stereoregularity of the polymers by polymerizing olefins using a catalyst comprising (A) a solid catalyst component prepared by contacting (a) a dialkoxymagnesium, (b) a tetravalent titanium halide compound, and (c) an electron donor compound one another, (B) an organoaluminum compound of the formula R<SUP>1</SUP><SUB>p</SUB>AlQ<SUB>3-p</SUB>, and (C) an aminosilane compound of the formula R<SUP>2</SUP>R<SUP>3</SUP>Si(OR<SUP>4</SUP>)<SUB>2</SUB>.
