Document Type and Number:
Japanese Patent JP6824012
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a catalyst component for olefin polymerization capable of preparing a catalyst for olefin polymerization capable of producing an olefin polymer having high catalytic activity and bulk density.SOLUTION: A method for producing a catalyst component (Sa) for olefin polymerization includes a step of reacting a component (A) being a predetermined organic aluminum compound and a component (B) being a predetermined organic aluminum oxy compound, and a component (C) being predetermined silica gel, where a molar ratio (aluminum atom of component (A)/aluminum atom of component (B)) of the component (A) reacting with the component (C) to an aluminum atom of the component (B) is 0.12 or more and 0.24 or less.SELECTED DRAWING: None
