    Abstract: The present disclosure provides for a liquid transition metal chelating polyol blend that can be used in an isocyanate-reactive composition and a reaction mixture for forming a polyurethane polymer. The liquid transition metal chelating polyol blend includes a polyol, a transition metal compound having a transition metal ion and a chelating agent having a nitrogen based chelating moiety, where the liquid transition metal chelating polyol blend has a molar ratio of nitrogen in the nitrogen based chelating moiety to the transition metal ion of 8:1 to 1:1 (moles nitrogen:moles of transition metal ion).

    Abstract: An olefin polymerization catalyst system includes a procatalyst component chosen from metal-ligand complexes of Formula (I): In Formula (I), each X is independently a monodentate or polydentate ligand that is neutral, monoanionic, or dianionic; the metal-ligand complex of Formula (I) is overall neutral; each Y1-Y4 and Y7-Y10 independently is selected from C or N such that six membered diaza (N2) or triaza (N3) rings are formed; wherein each R1 and R10 independently are chosen from (C1-C40) hydrocarbyl, substituted (C1-C40) hydrocarbyl, (C1-C40) heterohydrocarbyl, and substituted (C1-C40) heterohydrocarbyl or is absent; each R2, R3, R4, R7, R8, and R9 is chosen from hydrogen; (C1-C40) hydrocarbyl; substituted (C1-C40) hydrocarbyl; (C1-C40) heterohydrocarbyl; substituted (C1-C40) heterohydrocarbyl; halogen, nitro (NO2) or is absent; each R5 and R6 independently is chosen from (C1-C40) hydrocarbyl, substituted (C1-C40) hydrocarbyl, (C1-C40) heterohydrocarbyl, and substituted (C1-C40) heterohydrocarbyl.

    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.
