Abstract
A phthalic acid diester derivative represented by a specific formula and an electron donor used in an olefin polymerization catalyst containing the phthalic acid diester derivative as an effective component. The electron donor can produce polymers with a high stereoregularity at an extremely high polymerization activity and high yield, and exhibit a high response to hydrogen.
