    Abstract: The present disclosure relates to a catalyst system for use in forming a multi-block copolymer, said copolymer containing therein two or more segments or blocks differing in chemical or physical properties, a polymerization process using the same, and the resulting polymers, wherein the composition comprises the admixture or reaction product resulting from combining: (A) a first olefin polymerization procatalyst, (B) a second olefin polymerization procatalyst capable of preparing polymers differing in chemical or physical properties from the polymer prepared by procatalyst (A) under equivalent polymerization conditions, (C) an activator, and (D) a chain shuttling agent.

    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 R1 and R10 is a (C6-C40)aryl, substituted (C6-C40)aryl, (C3-C40)heteroaryl, or substituted (C3-C40)heteroaryl; each R2, R3, R4, R7, R8, and R9 is a hydrogen; (C1-C40)hydrocarbyl; substituted (C1-C40)hydrocarbyl; (C1-C40)heterohydrocarbyl; substituted (C1-C40)heterohydrocarbyl; halogen; or nitro (NO2) group; and each R5 and R6 is a (C1-C)alkyl; substituted (C1-C40)alkyl; or [(Si)1—(C+Si)40] 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.

    Abstract: An olefin polymerization catalyst system comprising: a procatalyst component comprising a metal-ligand complex of Formula (I) wherein each X is independently a monodentate or polydentate ligand that is neutral, monoanionic, or dianionic, wherein n is an integer, and wherein X and n are chosen such that the metal-ligand complex of Formula (I) is overall neutral; wherein each R1 and R5 independently is selected from (C1-C40)hydrocarbyls, substituted (C1-C40)hydrocarbyls; (C1-C40)heterohydrocarbyls and substituted (C1-C40)heterohydrocarbyls; wherein each R2 and R4 independently is selected from (C1-C40)hydrocarbyls and substituted (C1-C40)hydrocarbyls; wherein R3 is selected from the group consisting of a (C3-C40)hydrocarbylene, substituted (C3-C40)hydrocarbylene, [(C+Si)3-(C+Si)40]organosilylene, substituted [(C+Si)3-(C+Si)40]organosilylene, [(C+Ge)3-(C+Ge)40]organogermylene, or substituted [(C+Ge)3-(C+Ge)40]organogermylene; wherein each N independently is nitrogen; and optionally, two or more R1-5 groups each independently can combine together to form mono-aza ring structures, with such ring structures having from 5 to 16 atoms in the ring excluding any hydrogen atoms.
