Abstract: Processes of polymerizing olefin monomers and catalyst systems. The catalyst systems include a non-hydrogen-generating post-metallocene procatalyst; a co-catalyst; and a hydrogenation procatalyst having the formula Cp 2 TiX n TiCp 2 or Cp 2 TiX n , in which each Cp is cyclopentadienyl substituted with at least one (C 1 -C 10 )alkyl; each X is independently monoanionic or neutral, wherein each X is independently (C 1 -C 40 )hydrocarbon, (C 1 -C 40 )heterohydrocarbon, (C 1 -C 40 )hydrocarbyl, (C 1 -C 40 )heterohydrocarbyl, or a halogen atom; and n is 1 or 2.

Abstract: Embodiments of the disclosure include processes of polymerizing olefins. The process includes contacting ethylene and a (C 3 −C 40 )alpha-olefin comonomer in the presences of a catalyst system. The catalyst system comprises a procatalyst and a bimetallic activator complex. The bimetallic activator complex comprises an anion and a countercation, and the anion has a structure according to formula (I).
