Abstract:
A supported metallocene catalyst for olefin polymerization comprising solid fine particles which comprise a reaction product of a metallocene compound and aluminoxane supported on a fine particulate inorganic support, said solid fine particles being produced by carrying out in order of the following steps:(a) reacting a metallocene compound with an aluminoxane in an aromatic hydrocarbon solvent to form a reaction product, (b) contacting the reaction product with a fine particulate inorganic support at a temperature of 85 to 150Â° C. in the presence of any aromatic hydrocarbon solvent to form a solid product having the reaction product supported on said inorganic support, and (c) washing the solid product with an aliphatic hydrocarbon solvent at a temperature of âˆ’50Â° C. to +30Â° C.
