| abstract |
The invention encompasses late transition metal catalyst systems and their use in polymerization processes, particularly in solution, 2-phase suspension and super-critical phase polymerization of ethylene-containing polymers. Preferred embodiments include the use of a late transition metal catalyst system comprising a Group 9, 10, or 11 metal complex stabilized by a bidentate ligand structure for polymerization under elevated ethylene pressure, or concentration, conditions. |
