摘要： The invention encompasses late transition metal catalyst systems immobilized on solid supports and their use in heterogenous polymerization processes, particularly in gas phase polymerization of olefin monomers. Preferred embodiments include a late transition metal catalyst system comprising a Group 9, 10, or 11 metal complex stabilized by a bidentate ligand structure immobilized on a solid porous metal or metalloid oxide particle support, particularly those comprising silica. The gas phase polymerization process for olefin monomers comprises contacting one or more olefins with these catalyst systems under gas phase polymerization conditions.

摘要： An activated tridentate-, monoanionic-ligand-based transition metal catalyst in a reduced oxidation state for olefin polymerization is disclosed. Transition metal catalyst precursors for these catalysts have formulae (A), (B), in which M is a transition metal from Groups 4-9 in a reduced oxidation state, X is a monoanionic, ligand, L is a neutral donor group, E is a neutral donor group from Groups 15 and 16, E' is a monoanionic donor group from Group 15, T is a bridging group, n is 1-3 as needed to balance the charge on M, p is 0-3 and q is 1-2. Olefin polymerization is exemplified.
