| titleOfInvention | Method for producing a polyolefin |
| abstract | ABSTRACT A method for producing a polyolefin in the presence of a catalyst comprising a transition metal compound and an organometallic compound, which comprises polymerizing at least one .alpha.-olefin in the presence of a catalyst system comprising: (A) a solid catalyst component prepared by prepolymerizing (vi) at least one .alpha.-olefin in the presence of a solid composite obtained by reacting a homogeneous solution containing (i) at least one member selected from the group consisting of metal magnesium and a hydroxylated organic compound, and oxygen-containing organic compounds of magnesium, (ii) at least one oxygen-containing organic compound of titanium and (iii) at least one silicon compound, with (iv) at least one organoaluminum halide compound, and (v) at least one member selected from the group consisting of organometallic compounds of metals of Groups Ia, IIa, IIb, IIIb and IVb of the Periodic Table, and (B) at least one member selected from the group consisting of organometallic compounds of metals of Groups Ia, IIa, IIb, IIIb and IVb of the Periodic Table. According to the present invention, a polyolefin can be obtained by one catalyst system at high productivity and catalytic activity irrespective of the range of density and polymerization method. |
