Abstract
Olefin polymerization catalyst systems are provided that include a procatalyst component having a metal-ligand complex of Formula (I): [formula] (I) where each X is a neutral, monoanionic, or dianionic, monodentate or polydentate ligand such that the complex of Formula (I) is neutral; each Rand Ris a (C-C)aryl, substituted (C-C)aryl, (C-C)heteroaryl, or substituted (C-C)heteroaryl; each R, R, R, R, R, and Ris a hydrogen; (C-C)hydrocarbyl; substituted (C-C)hydrocarbyl; (C-C)heterohydrocarbyl; substituted (C-C)heterohydrocarbyl; halogen; or nitro (NO) group; and each Rand Ris a (C-C)alkyl; substituted (C-C)alkyl; or [(Si)—(C+Si)] substituted organosilyl. Additionally, olefin-based polymers and processes for polymerizing one or more olefin-based polymers in the presence of the olefin polymerization catalyst systems are also provided.
