Patent ID: 7371803

Claim:
A process to polymerize unsaturated monomers comprising contacting monomers with a catalyst system comprising an activator and a transition metal catalyst compound represented by formula 1 or formula 2: wherein each M is, independently, a group 7, 8, 9, 10, or 11 transition metal; N is nitrogen; C is carbon; each X is, independently, an anionic monodentate ligand, or both X groups together may form a bidentate dianionic ligand; each R′ is, independently, a hydrogen, a hydrocarbyl, a substituted hydrocarbyl, a halocarbyl, or a substituted halocarbyl; independently, two R′ groups on the same carbon may join to form a cyclic or polycyclic ring structure; when x is 2, 3, or 4, and or when y is 2, 3, or 4, two or more R′ groups on adjacent carbon atoms may join to form a cyclic or polycyclic ring structure; each x is, independently, 1, 2, 3 or 4; each y is, independently, 1, 2, 3 or 4; each R 1 and R 3 is, independently, a hydrogen, hydrocarbyl or halocarbyl; each R 2 and R 4 is, independently, a C 3 to C 50 hydrocarbyl or a C 3 to C 50 halocarbyl; and each R 6 , R 7 , R 8 , or R 9 is, independently, a hydrogen, a hydrocarbyl, a substituted a hydrocarbyl, a halocarbyl, or a substituted halocarbyl, or independently, two adjacent R 6 , R 7 , R 8 , or R 9 may join together to form a cyclic or polycyclic ring structure.
