Patent

CA 2193882

This invention is generally directed toward a supported catalyst system useful for polymerizing olefins. The method for supporting the catalyst system of the invention provides for a supported metallocene catalyst and alumoxane activator which when utilized in a polymerization process substantially reduces the reactor fouling and sheeting.

La présente invention se rapporte généralement à un système catalyseur supporté utile dans la polymérisation d'oléfines. Le procédé de support de ce système catalyseur a recours à un catalyseur à base de métallocène supporté et à un activateur alumoxane réduisant sensiblement l'encrassement du réacteur et la formation de dépôts lors d'un processus de polymérisation.
