Abstract

A solid catalyst component for olefin polymerization includes titanium, magnesium, a halogen, a compound represented by (R)CH(COOR)(COOR), and a compound represented by RO—C(═O)—O—Z—OR. The solid catalyst component is a novel solid catalyst component for olefin polymerization that achieves excellent olefin polymerization activity and activity with respect to hydrogen during polymerization, and can produce an olefin polymer that exhibits a high MFR, high stereoregularity, and excellent rigidity.
