Abstract:
Provided is a solid catalyst component for olefin polymerization comprising an electron-donating compound other than a phthalate, the solid catalyst component being equal in the olefin-polymerizing activity and in the primary physical properties of the resulting polymer such as stereoregularity and molecular weight distribution to those with use of a phthalate as an electron-donating compound. A solid catalyst component for olefin polymerization comprises a magnesium atom, a titanium atom, a halogen atom, an ester compound (A) represented by a general formula (1) and a diester compound (B) represented by a general formula (2), wherein
a ratio represented by the following expression: (content (mass %) of ester compound (A)/content (mass %) of diester compound (B)) is 0.05 to 50.
a ratio represented by the following expression: (content (mass %) of ester compound (A)/content (mass %) of diester compound (B)) is 0.05 to 50.
