Catalyst compound containing divalent tridentate ligand

摘要

This invention relates to a catalyst compound represented by the formula: wherein: M is a Group 3 to 12 transition metal; each R^a is, independently, a hydrogen, a hydrocarbyl group, a substituted hydrocarbyl group or halogen; each of R¹, R², R³, R⁴, R⁵, R⁷, R⁸, R⁹, R¹⁰, and R¹¹ is, independently a hydrogen, a hydrocarbyl group, a substituted hydrocarbyl group or halogen; R⁶ is hydrogen, a hydrocarbyl group, or a substituted hydrocarbyl group; x is 0, 1, 2, 3 or 4; and each Z is, independently, a group 15 atom. This invention also relates to catalyst systems comprising the above catalyst compound and a activator and the use of such catalyst systems to polymerize monomers, including olefin monomers.
