The present invention relates to functionalized catalyst supports that are useful in the formation of supported polymerization catalysts, supported catalysts derived from such functionalized catalyst supports, methods for preparing such functionalized catalyst supports and supported catalysts, and polymerization processes utilizing such supported catalysts. The functionalized catalyst support comprises a particulated support material having chemically bonded thereto a plurality of aluminum-containing groups derived from a non-ionic Lewis acid, said aluminum-containing groups: containing at least one fluoro- substituted hydrocarbyl ligand containing from 1 to 20 carbons, said hydrocarbyl ligand being bonded to aluminum, and being bonded to said support material, optionally through a bridging moiety, said composition being capable of activating a Group 3-10 metal complex for the addition polymerization of one or more addition polymerizable monomers.
L'invention concerne des supports catalytiques fonctionnalisés servant à produire des catalyseurs de polymérisation sur supports, des catalyseurs sur supports dérivés de ces supports catalytiques fonctionnalisés, les procédés de préparation de ces supports catalytiques fonctionnalisés et des catalyseurs sur supports, et des procédés de polymérisation où l'on utilise ces catalyseurs sur supports. Le support catalytique fonctionnalisé comprend une matière support particulaire liée chimiquement à plusieurs groupes contenant de l'aluminium dérivés d'un acide de Lewis non-ionique. Lesdits groupes contiennent au moins un ligand d'hydrocarbyle substitué au fluor possédant 1 à 20 carbones, ledit ligand étant lié à l'aluminium, et à ladite matière support, éventuellement par une fraction de pontage. Ladite composition peut activer un complexe de métal du groupe 3-10 pour polymériser par addition au moins un monomère polymérisable par addition.
