    摘要: Processes are provided that produce organo-aluminoxane compositions. Said processes comprise: desiccating a first mixture, where said first mixture comprises organo-aluminoxane molecules intermixed with a solvent, to produce a first composition, where said first composition comprises organo-aluminoxane molecules; mixing said first composition with a solvent to produce a second mixture, where said second mixture comprises organo-aluminoxane molecules and said solvent; contacting said second mixture with a insolublization agent to produce said organo-aluminoxane compositions. A polymerization process using a catalyst that comprises an organo-aluminoxane composition is also provided.
