1. 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:
 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 R1 and R3 is, independently, a hydrogen, hydrocarbyl or halocarbyl;
each R2 and R4 is, independently, a C3 to C50 hydrocarbyl or a C3 to C50 halocarbyl; and
each R6, R7, R8, or R9 is, independently, a hydrogen, a hydrocarbyl, a substituted a hydrocarbyl, a halocarbyl, or a substituted halocarbyl, or independently,
two adjacent R6, R7, R8, or R9 may join together to form a cyclic or polycyclic ring structure.
