PROBLEM TO BE SOLVED: To obtain a new highly hydrogen-sensitive, highly active organic silicon compound useful as a component for catalysts for polymerizingα-olefins to give highly stereoregularα-olefin polymers having wide mol.wt. distributions. SOLUTION: A compound of the formula (R1 is a 1-8C hydrocarbon; R2 is H or a 1-12C hydrocarbon; R3 is a 2-24C hydrocarbon, a 1-24C hydrocarbon alkoxy or the like; X is 0-12; Y, Z are each 2-12), for example, ethyl(4,4- pentamethylenepiperidino)dimethoxysilane. This compound is obtained, for example, by reacting an alkyltrimethoxysilane such as ethyltrimethoxysilane with the equivalent amount of a hydrocarbon amine Mg or Li salt such as 4,4- pentamethylene piperidine Li salt. The 4,4-pentamethylene piperidine Li salt is obtained, for example, from 1,1-cyclohexane diacetic acid as a starting substance. Anα-olefin is polymerized in the presence of a catalyst comprising an organic aluminum compound, the compound of the formula and a solid catalyst component consisting essentially of magnesium, titanium, a halogen element and an electron donor.
