Abstract:
1. A process for producing a solid catalyst component for olefin polymerization, which comprises the step of contacting a solid catalyst component precursor (C) containing a magnesium atom, a titanium atom and a hydrocarbyloxy group, the hydrocarbyloxy group having 1 to 20 carbon atoms, with a halogeno compound (A) of the 13 or 14 group of elements in the periodic table of the elements, and an electron donor (B), the electron donor being selected from the group consisting of an organic acid esters, and an ethers, wherein the solid catalyst component precursor (C) is a trivalent titanium atom-containing solid product obtained by reducing a titanium compound (2) represented by the following formula, wherein R 1 is a hydrocarbon group having 1 to 20 carbon atoms, X is a halogen atom, and “a” is a number satisfying 0<a≦4 with an organomagnesium compound (3) in the presence of an organosilicon compound (1) having an Si—O bond.
