(57) [Summary] [Structure] At least one member selected from the group consisting of metal Mg, a hydroxylated organic compound, and an oxygen-containing organic compound of Mg, Zr At least one halogenated compound in a homogeneous solution containing at least one Zr compound selected from oxygen-containing organic compounds and halogen-containing compounds, and at least one Si-based compound selected from polysiloxanes and silanes. A method for producing ultrahigh molecular weight polyethylene, which comprises using a catalyst system comprising a solid catalyst component produced by reacting organic Al and at least one selected from organic Al compounds. [Effect] The particle shape is good and the intrinsic viscosity [η] is 5 dl / Ultra high molecular weight polyethylene of g or more is produced. |
