    Abstract: A solid catalyst component for polymerization of olefins, a catalyst for polymerization of olefins, and a method for producing an olefin polymer are provided. The solid catalyst component (A) is obtained by causing a solid component (a) containing magnesium, titanium, and a halogen atom to come in contact with an organosilicon compound (b) shown by the formula, [CH2=CH—(CH2)n]qSiR14-q. A catalyst for polymerization of olefins (B) is formed from an organoaluminum compound shown by the formula R2rAlQ3-r. A process for producing an olefin polymer comprises polymerizing olefins in the presence of the catalyst. By using the catalyst, a polymer which has high catalyst activity and stereoregularity and is excellent in maintaining activity can be obtained in a high yield.
