| titleOfInvention | Process for producing catalyst for alpha-olefin polymerization, and process for producing alpha-olefin polymer |
| abstract | There are provided (I) a process for producing a catalyst for α-olefin polymerization, which comprises the steps of: n (1) reducing a specific titanium compound with an organomagnesium compound in the presence of an organosilicon compound having an Si—O bond to produce a reduction solid, n (2) aging the reduction solid for at least 18 hours in an inert solvent under stirring intermittently to produce a solid product. n (3) contacting the solid product with an ether compound, titanium tetrachloride and an organic acid halide compound, and then heating a resultant mixture to produce an organic acid halide-treated solid, n (4) contacting the organic acid halide-treated solid with a mixture of an ether compound, titanium tetrachloride and an ester compound, or with a mixture of an ether compound and titanium tetrachloride, and then heating a resultant mixture to produce a solid catalyst component containing a titanium compound, and n (5) contacting the solid catalyst component with an aluminum compound and an electron donor compound to produce a catalyst for α-olefin polymerization; and (II) a process for producing an α-olefin polymer, which comprises the step of homopolymerizing an α-olefin, or copolymerizing at least one kind of an α-olefin and ethylene in the presence of a catalyst produced by the above-mentioned process. |
