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 o f 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. |
