Abstract
, and an organoaluminum compound to come in contact with a solid component comprising magnesium, titanium, halogen, and an electron donor compound, or a solid catalyst component obtained by causing a magnesium compound, two types of titanium compounds, an electron donor compound, and an organosilicon compound to come in contact with each other, and (B) an organoaluminum compound. The process for producing an olefin polymer or copolymer comprises polymerizing olefins in the presence of the catalyst. The catalyst has a high catalytic activity, exhibits excellent hydrogen response, and can produce polymers with high stereoregularity and a broad molecular weight distribution at a high yield.
