Abstract:
A process for producing an olefin polymer comprising contacting at least one olefin with a catalyst system resulting from the combination of a transition metal-containing polymerization catalyst and an organo-aluminoxane composition produced by(a) 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 and where said first composition is a solid; (b) mixing said first composition with a solvent to produce a second mixture, where said second mixture comprises organo-aluminoxane molecules and said solvent; and (c) contacting said second mixture with an insolublization agent to produce said organo-aluminoxane compositions.
