Title: AN OLEFIN POLYMERIZATION CATALYST
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-C-40)heterohydrocarbyls and substituted (C1-C40)heterohydrocarbyls; wherein each R2 and R4 independently is selected from (C1-C40)hydrocarbyls andsubstituted (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.
