1,5 diazabicyclooctane ligand systems and methods therewith

A process for producing a copolymer, comprising:

• contacting one or more C2 to C20 olefin monomers with a catalyst system comprising a catalyst compound, activator, and optionally a support at a temperature, a pressure, and for a period of time sufficient to produce the polymer, the catalyst compound represented by Formula (I):
• where
• M is a Group 3-13 metal having a valance equal to Z;
• each L is a univalent C1 to C40 hydrocarbyl radical comprising elements from Groups 13-17 of the periodic table of the elements, a univalent functional group comprising elements from Groups 13-17 of the periodic table of the elements, or a combination thereof;
• each L′ is a divalent C1 to C40 hydrocarbyl radical comprising elements from Groups 13-17 of the periodic table of the elements, a divalent functional group comprising elements from Groups 13-17 of the periodic table of the elements, or a combination thereof;
• a is greater than or equal to 0 and less than or equal to Z−2;
• b is greater than or equal to 0 and less than or equal to Z−2;
• and Z−2−(a)−(2b)=0;
• each of R1, R2, R3, R4, R5, R6, R7, R8, R9, R10, R11, R12, R13, R14, R15, R16, R17, R18, and R19 is, independently, a hydrogen, a C1-C40 hydrocarbyl radical, a functional group comprising elements from Group 13-17 of the periodic table of the elements, or two or more of R1 to R19 are independently optionally joined together to form a C4 to C62 cyclic or polycyclic ring structure, or a combination thereof.
