The present disclosure relates to Lewis base catalysts. Catalysts, catalyst systems, and processes of the present disclosure can provide high temperature ethylene polymerization, propylene polymerization, or copolymerization. In at least one embodiment, the catalyst compounds belong to a family of compounds comprising amido-phenolate-heterocyclic ligands coordinated to group 4 transition metals. The tridendate ligand may include a central neutral hetrocyclic donor group, an anionic phenolate donor, and an anionic amido donor. In some embodiments, the present disclosure provides a catalyst system comprising an activator and a catalyst of the present disclosure. In some embodiments, the present disclosure provides a polymerization process comprising a) contacting one or more olefin monomers with a catalyst system comprising: i) an activator and ii) a catalyst of the present disclosure.

Lewis base catalysts and methods thereof

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, R, R, R, R, R, R, R, R, A, A, are as defined herein, where AQAare part of a heterocyclic Lewis base containing 4 to 40 non-hydrogen atoms that links Ato Avia a 3-atom bridge with Q being the central atom of the 3-atom bridge.

Transition metal bis(phenolate) complexes and their use as catalysts for olefin polymerization

This invention relates to transition metal complexes represented by the formula: catalyst systems comprising the complexes, and polymerization methods for olefinic monomers using the catalyst systems. In said formula, M is a transition metal; E is NR, CRR, O, S, or SiRR; Q is optional substitution; p is an integer ranging from 0 to 3; L is an optional neutral ligand; m is an integer ranging from 0 to 3; X is an anionic leaving group; n is 1 or 2, with m+n being 4 or less; J is a linker group contributing two or three atoms that are located within a first chelate ring; Rand Rare independently a hydrocarbyl group or a trihydrocarbylsilyl group; Ris a hydrocarbyl group; Rand Rare independently H, a hydrocarbyl group, or a trihydrocarbylsilyl group; and Rand Rare independently a hydrocarbyl group.

Benzazole and pseudoindole diamido transition metal complexes and use thereof in olefin polymerization

Quinolinyldiamido transition metal complexes are disclosed for use in alkene polymerization to produce multimodal polyolefins.

Quinolinyldiamido transition metal complexes, production and use thereof

The present disclosure provides methods for making quinolinyldiamine products from quinolinyl starting materials. In addition, the quinolinyldiamines can be used as ligands or ligand precursors for catalysts, e.g. for use in olefin polymerization.

Methods for making quinolinyldiamines

This invention relates to a novel group 2, 3 or 4 transition metal metallocene catalyst compound having at least one arenyl ligand substituted with: 1) a cyclopropyl group and, optionally, 2) at at least one other group, such as a hydrocarbyl, a heteroatom or a heteroatom containing group.

Cyclopropyl substituted metallocene catalysts
