Surprisingly stable olefin polymerization catalysts and co-catalysts formed from hydroxyaluminoxanes are revealed. In one embodiment of the invention, a solid composition of matter is formed from a hydroxyaluminoxane and a treating agent, whereby the rate of OH-decay for the solid composition is reduced as compared to that of the hydroxyaluminoxane. Gelatinous compositions of matter formed from hydroxyaluminoxane and having similar stabiltiy characteristics are also disclosed. Processes for converting a hydroxyaluminoxane into a such compositions of matter, supported catalysts formed from such co-catalyst compositions of matter, as well as methods of their use, are described.
L'invention concerne des catalyseurs et des cocatalyseurs de polymérisation d'oléfines étonnamment stables, formés à partir d'hydroxyaluminoxanes. Dans un mode de réalisation de cette invention, une composition solide est formée à partir d'un hydroxyaluminoxane et d'un agent de traitement, le taux de dégradation de OH pour ladite composition solide étant diminué comparé à celui de l'hydroxyaluminoxane. L'invention concerne également des compositions gélatineuses formées à partir d'hydroxyaluminoxane et possédant des caractéristiques de stabilité similaires. L'invention concerne également des procédés permettant de convertir un hydroxyaluminoxane en une telle composition, des catalyseurs supportés formés à partir de telles compositions de cocatalyseurs, ainsi que leurs procédés d'utilisation.
