CATALYST COMPOSITION |
摘要 |
This invention relates to catalyst compounds, catalysts systems and methods to oligomerize or polymerize monomers where the catalyst compound and the catalyst system comprise compounds of formula: LMX2 or (LMX2)2 wherein: M is a Group 7, 8, 9, 10 or 11 transition metal; L is a tridentate or tetradentate neutrally charged ligand that is bonded to M by at least three nitrogen atoms; at least one of the nitrogen atoms is a central non-pyridinal nitrogen atom and is not bonded to its adjacent atoms by a multibond; at least two of the nitrogen atoms are terminal nitrogen atoms; at least one terminal nitrogen atom is part of a pyridinyl ring; at least one other terminal nitrogen atom is substituted with at least one C3-C50 hydrocarbyl or halobydrocarbyl; the central nitrogen atom is bonded to at least two different carbon atoms; and each X is an anionic monodentate ligand. |
