Abstract:
A process for producing a solid catalyst component (1) for &agr;-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 Siâ€”O bond, thereby obtaining a solid product, and (2) contacting the solid product with 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 &agr;-olefin polymerization, wherein â€œaâ€  is a number of 2 to 20, R2 is a hydrocarbon group having 1 to 20 carbon atoms, and X2 is a halogen atom or a hydrocarbyloxy group having 1 to 20 carbon atoms, and all of X2 may be the same or different from one another.
