Abstract: The present invention is directed toward Group 4, 5, 6, 7, 8, 9, 10 or 11 transition metal compounds containing neutral, mono- or di-anionic tridentate nitrogen/oxygen based ligands that are useful, with or without activators, to polymerize olefins, particularly ?-olefins, or other unsaturated monomers. For the purposes of this disclosure, “?-olefins” includes ethylene. The present invention is also directed toward Group 4, 5, 6, 7, 8, 9, 10 or 11 transition metal compounds containing neutral, bidentate nitrogen/oxygen based ligands that are useful to polymerize olefins, particularly ?-olefins, or other unsaturated monomers.

Abstract: This invention relates to new transition metal catalyst compounds represented by the formula (I): where: M and M? are, independently, a group 8, 9, 10 or 11 transition metal, preferably Ni, Co, Pd, Cu or Fe; each R group is, independently, is, hydrogen, or a hydrocarbyl, substituted hydrocarbyl, halocarbyl, substituted halocarbyl, silylcarbyl, substituted silylcarbyl, germylcarbyl, or substituted germylcarbyl substituents, and optionally, adjacent R groups may join together to form a substituted or unsubstituted, saturated, partially unsaturated, or aromatic cyclic or polycyclic substituent; R? is hydrogen, or a hydrocarbyl, substituted hydrocarbyl, halocarbyl, substituted halocarbyl, silylcarbyl, substituted silylcarbyl, germylcarbyl, or substituted germylcarbyl substituents, and optionally, adjacent R groups may join together with R? to form a substituted or unsubstituted, saturated, partially unsaturated, or aromatic cyclic or polycyclic substituent; each X group is, independently, is, hydrogen, a halo

Abstract: 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 halohydrocarbyl; the central nitrogen atom is bonded to at least two different carbon atoms; and each X is an anionic monodentate ligand.
