    摘要: The present invention provides a chemically-modified support comprising an inorganic oxide containing optionally functionalized hydroxyl groups, having chemically linked thereto the cation of a cation/anion pair. The present invention further provides a supported catalyst system comprising the chemically-modified support as described above, and a transition metal compound of Groups 3-10 (preferably a Group 4 metal compound) containing at least one π-bonded anionic ligand group, said transition metal compound being capable of reacting with the chemically-modified support through the cation of the cation/anion pair to thereby render the transition metal compound catalytically active. The present invention further provides a process for preparing the chemically-modified support of the invention. The present invention further provides an addition polymerization process comprising contacting one or more addition polymerizable monomers with the supported catalyst system of the invention under addition polymerization conditions.
