A supported catalyst for olefin polymerization comprises a combination of a novel metal oxide support and an activator which is an aluminoxane or a boron activator. The novel metal oxide support of this invention is a conventional particulate metal oxide support material (such as silica or alumina) which has been treated with a halosulfonic acid. A catalyst system which contains this novel catalyst support and a transition metal catalyst is highly active for olefin polymerization (in comparison to prior art catalyst systems which use a conventional metal oxide support).
Catalyseur d'appui pour la polymérisation d'oléfines, qui comprend une combinaison d'un nouveau support d'oxyde métallique et d'un activateur, à savoir un aluminoxane ou un activateur de bore. Le nouveau support d'oxyde métallique de la présente invention est un matériau de support d'oxyde métallique conventionnel sous forme de particules (comme la silice ou l'alumine) qui a été traité avec un acide halosulfonique. Un système catalytique qui contient ce nouveau support catalytique et un catalyseur de métal de transition est très actif pour la polymérisation d'oléfine (comparativement aux systèmes catalyseurs antérieurs qui utilisent un support d'oxyde métallique conventionnel).
