titleOfInvention |
α-Olefin polymerization catalyst and process for producing α-olefin polymer |
abstract |
An α-olefin polymerization catalyst comprising (A) a solid catalyst component containing a titanium compound obtained by treating a solid product having a titanium content of 1.5% by weight or less obtained by reducing Ti(OR 1 ) a X 4-n (R 1 represents a hydrocarbon group having 1 to 20 carbon atoms, X represents a halogen atom and a represents a number satisfying 0<a≦4.) with an organomagnesium compound in the presence of an organosilicon compound having an Si—O bond and an ester compound, with an ester compound, and treating the ester-treated solid with a mixture of an ether compound and titanium tetrachloride or a mixture of an ether compound, titanium tetrachloride and an ester compound, (B) an organoaluminum compound and (C) an electron donative compound, and a process for producing an α-olefin polymer with said α-olefin polymerization catalyst. |
