Patent ID: 6841503

Claim:
A process for the producing a solid catalyst component (1) for α-olefin polymerization, which comprises the steps of: (1) reducing a titanium compound represented by the following formula [I] with an organomagnesium compound in the presence of an organosilicon compound having an Si—O bond, thereby obtaining a solid product, and (2) contacting the solid product with a halogeno compound of a Group 14 element selected from the group consisting of Si, Ge, Sn and Pb; and at least one member selected from the group consisting of an electron donor compound (E1) and an organic acid halide, and a compound having a Ti-halogen bond, thereby obtaining the solid catalyst component (1) for α-olefin polymerization, wherein “a” is a number of 1 to 20, R 2 is a hydrocarbon group having 1 to 20 carbon atoms, and X 2 is a halogen atom or a hydrocarbyloxy group having 1 to 20 carbon atoms, and all of X 2 may be the same or different from one another.
