(57) [Summary]nThe present invention relates to a mixed transition metal olefin polymerization catalyst system suitable for the polymerization of olefin monomers, comprising one late transition metal catalyst system and a late transition metal catalyst system, a transition metal metallocene catalyst system, or a Ziegler-Natta catalyst system. A mixed transition metal olefin polymerization catalyst system comprising at least one different catalyst system selected from the group consisting of: Preferred embodiments include at least one late transition metal catalyst system comprising a Group 9, 10, or 11 metal complex stabilized by a bidentate ligand structure, and at least one auxiliary cyclopentadienyl ligand. At least one transition metal metallocene catalyst system comprising a Group 4 metal complex stabilized by a ligand. The process for polymerizing olefin monomers involves contacting one or more olefins with these catalyst systems under polymerization conditions. |
