Abstract:
An olefin polymer that is obtained using an olefin polymerization catalyst that includes a solid catalyst component for olefin polymerization that includes titanium, magnesium, a halogen, and an ester compound (A) represented by the following formula (1): R1R2C═C(COOR3)(COOR4), an organoaluminum compound, and an optional external electron donor compound, exhibits primary properties (e.g., molecular weight distribution and stereoregularity) similar to those of an olefin polymer obtained using a solid catalyst component that includes a phthalic ester as an electron donor.
