摘要：A process for preparing premixed supported boraaryl catalysts having improved shelf life is provided. The process comprises supporting an organometallic compound comprising a group 3-10 transition metal or lanthanide metal and at least one boraaryl ligand an inorganic support which has been chemically and thermally dehydroxylated to remove all hydroxyl from the surface of the support; contacting with an organoaluminum compound utilizing an incipient wetness procedure wherein 90 to 150 percent of the catalyst pore volume is filled with a hydrocarbon solution containing the organoaluminum and provide a molar ratio of aluminum to transition/lanthanide metal of 0.5:1 to 50:1; and recovering the premixed catalyst powder.
