Abstract: The present disclosure relates to amido-benzoquinone transition metal complexes, catalyst systems including amido-benzoquinone transition metal complexes, and polymerization processes to produce polyolefin polymers such as polyethylene-based polymers and polypropylene-based polymers.

Abstract: This invention relates to transition metal complexes of a dianionic, tridentate ligand that features a central neutral heterocyclic Lewis base and two phenolate donors, where the tridentate ligand coordinates to the metal center to form two eight-membered rings. Preferably the bis(phenolate) complexes are represented by Formula (I): where M, L, X, m, n, E, E?, Q, R1, R2, R3, R4, R1?, R2?, R3?, R4?, A1, A1?, are as defined herein, where A1QA1? are part of a heterocyclic Lewis base containing 4 to 40 non-hydrogen atoms that links A2 to A2? via a 3-atom bridge with Q being the central atom of the 3-atom bridge.

Abstract: The present disclosure provides borate or aluminate activators comprising cations having linear alkyl groups, catalyst systems comprising, and methods for polymerizing olefins using such activators. Specifically, the present disclosure provides activator compounds represented by Formula: [R1R2R3EH]d+[Mk+Qn]d-, wherein: E is nitrogen or phosphorous; d is 1, 2 or 3; k is 1, 2, or 3; n is 1, 2, 3, 4, 5, or 6; n?k=d; R1 is C1-C20 linear alkyl group; each of R2 and R3 is a C1-C40 linear alkyl group, a meta- and/or para-substituted phenyl group, an alkoxy group, a silyl group, a halogen, or a halogen containing group, wherein R1+R2+R3?15 carbon atoms; M is an element selected from group 13, typically B or Al; and each Q is independently a hydride, bridged or unbridged dialkylamido, halide, alkoxide, aryloxide, hydrocarbyl, substituted hydrocarbyl, halocarbyl, substituted halocarbyl, or halosubstituted-hydrocarbyl radical, provided that when Q is a fluorophenyl group, then R2 is not a C1-C40 linear alkyl group.

Abstract: This invention relates to a polymerization catalyst system comprising group 8 or 9 containing non-coordinating anion activator, a polymerization catalyst compound, optional support, and optional scavenger. Preferably, the activator comprises a compound represented by the formula: Hs(L)mM where M is a group 8 or 9 metal, s is 0 or 1, m 1, 2, 3, or 4, each L ligand is independently C?O, NR3, PR3, where each R, independently is halogen, haloalkyl, or haloaryl) or optionally two or more L ligands may together form a multiply-valent ligand complex.
