| titleOfInvention | Process for producing alpha-olefin polymer |
| abstract | ABSTRACT OF THE DISCLOSURE A solid catalyst component containing a trivalent titanium compound, which is obtained by reducing a titanium compound represented by the general formula Ti(OR1)nX4-n (wherein R1 is a hydrocarbon group of 1 to 20 carbon atoms; X is a halogen atom; and n is a number satisfying O<n?4) with an organomagnesium compound in the presence of an organosilicon compound having at least one Si-O bond and a silica gel having a pore volume of, at a pore radius of 75 to 20,000 .ANG., at least 0.65 ml/g to obtain a solid product, treating the solid product with an ester compound, and treating the ester-treated solid with a mixture of an ether compound and titanium tetrachloride; a catalyst system comprising: (A) said solid catalyst component, (B) an organoaluminum compound, and (C) a silicon compound having at least one Si-OR2 bond (wherein R2 is a hydrocarbon group having 1 to 20 carbon atoms) for alpha-olefin polymerization; and a process for producing an alpha-olefin polymer, which comprises homopolymerizaing an alpha-olefin or copolymerizing alpha-olefins using said catalyst system. |
