OLEFIN POLYMERIZATION CATALYST SYSTEM

摘要

This invention relates to a catalyst precursor compound comprising a tridentate phenoxy-amide-amine group bound to a group 3 to 12 metal or lanthanide metal. In particular, this invention relates to a catalyst precursor compound represented by the formula wherein: M is a group 3 to group 12 transition metal or lanthanide metal, provided however N' is not part of a pyridine ring when M is a group 8, 9, or 10 metal; Q is oxygen or sulfur; N is nitrogen; N<1> is nitrogen; R1, is a hydrogen, a hydrocarbyl, a substituted hydrocarbyl, a halocarbyl, a substituted halocarbyl, a heteroatom or heteroatom containing group; R2 and R3 are independently, a hydrogen, a halogen, a hydrocarbyl, a substituted hydrocarbyl, a halocarbyl, or a substituted halocarbyl, a heteroatom or heteratom containing group and R2 and R3 together may form a multidentate ligand, such as a bidentate dianionic ligand; R4 is hydrogen, a hydrocarbyl, a substituted hydrocarbyl, a halocarbyl, a substituted halocarbyl, a heteroatom or heteroatom containing group; R5 is a hydrogen, a hydrocarbyl, a substituted hydrocarbyl, a halocarbyl, a substituted halocarbyl, a heteroatom or heteroatom containing group; R6, R7, and R8 are, independently, a hydrogen, a hydrocarbyl, a substituted hydrocarbyl, a halocarbyl, a substituted halocarbyl, a heteroatom or heteroatom containing group, and any two of R1, R6, R7, and R8 may form a fused ring system; each R9 is, independently, hydrogen, a hydrocarbyl, a substituted hydrocarbyl, a halocarbyl, a substituted halocarbyl group, or a heteroatom or heteroatom containing group; R10 is a hydrocarbyl, a substituted hydrocarbyl, a halocarbyl, a substituted halocarbyl group, or a heteroatom or heteroatom containing group; where any two adjacent R groups may form a ring structure.
