    摘要： A solid polymethylaluminoxane composition is provided having uniform particle diameter in the form of fine particles of less than 5 μm employed to polymerize olefins with high polymerization activity without silica. A method for manufacturing thereof, a polymerization catalyst, and a method for manufacturing a polyolefin are also provided. The solid polymethylaluminoxane composition: has an aluminum content within a range of 36 mass % to 43 mass %; has a mole fraction of methyl groups derived from trimethylaluminum moieties relative to the total number of mols of methyl groups of 12 mol % or less; and is particulate having a median diameter based on volume within a range of 0.1 μm to less than 5 μm. In a step of heating an aromatic hydrocarbon solution containing trimethylaluminum and the polymethylaluminoxane to cause solid polymethylaluminoxane composition to precipitate, prior to or during the heat treating step, a dry, inert gas is bubbled through.

    摘要： An olefin polymerisation titanium catalyst. It comprises a titanium compounds and an organoaluminium compound cocatalyst supported on a soluble polysulfone comprising free reactive sulfone groups. The molar ratio of titanium to aluminium is 1-10:200 and the weight ratio of titanium to polysulfone is 0.01-0.1:0.3-2.5. The process for preparing the catalyst comprises preparing a supported titanium compound by contacting a solution of a polysulfone in a halogenated or polar solvent with a titanium compound or a solution thereof in a halogenated or polar solvent in an inert atmosphere at a temperature between 10° C. and the boiling point of the solvent such that the weight ratio of titanium to polysulfone is 0.01-0.1:0.3-2.5.
