Patent

CA 2207459

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.

Il s'agit de procédés permettant de produire un composé d'organo-aluminoxanes. Ces procédés comprennent : la déshydratation d'un premier mélange comprenant des molécules organo- aluminoxanes mélangées à un solvant, ce qui produit un premier composé contenant des molécules organo-aluminoxanes; le mélange de ce premier composé avec un solvant pour produire un deuxième mélange formé de molécules organo-aluminoxanes et dudit solvant; la mise en contact de ce deuxième composé avec un agent d'insolubilisation pour produire lesdites compositions d'organo-aluminoxanes. On fournit aussi un processus de polymérisation au moyen d'un catalyseur, processus qui inclut la composition d'organo-aluminoxanes.
