Abstract:
A solid catalyst component for olefin polymerization comprising a titanium atom, a magnesium atom, a halogen atom, and a cycloheptapolyenedicarboxylic diester; a production method of the solid catalyst component, by contacting with one another a titanium compound, a magnesium compound, and the cycloheptapolyenedicarboxylic diester; a production method of a solid catalyst, by contacting the solid catalyst component with an organoaluminum compound; and a production method of an olefin polymer by polymerizing an olefin in the presence of the solid catalyst.
