| titleOfInvention | Method for producing a polyolefin |
| abstract | A method for producing a polyolefin in the presence of a catalyst comprising a transition metal compound and an organometallic compound, wherein a catalyst system is used which comprises: (A) a solid catalyst component prepared by reacting a homogenous solution containing (I) at least one member selected from the group consisting of (i) metal magnesium and a hydroxylated organic compound, and (ii) oxygen-containing organic compounds of magnesium, (II) an electron donative compound and (III) an oxygen-containing organic compound of titanium, with (IV) at least one aluminum halide compound to obtain a solid product, adding to this solid product (V) at least one compound selected from the group consisting of oxygen-containing organic compounds of one or more transition metals of Group IVb of the Periodic Table, and then treating the mixture with (VI) an aluminum halide compound, and (B) at least one catalyst component selected from the group consisting of organoaluminum compounds. A polymer having a desired molecular weight distribution and good configuration of particles can be obtained while maintaining high activity by the method of the present invention. |
