Metal complexes comprising certain polydentate heteroatom containing ligands, catalysts, and coordination polymerization processes employing the same are suitably employed to prepare polymers having desirable physical properties.

Polydentate heteroatom ligand containing metal complexes, catalysts and methods of making and using the same

Ligands, compositions, and metal-ligand complexes that incorporate phenol-heterocyclic compounds are disclosed that are useful in the catalysis of transformations such as the polymerization of monomers into polymers. The catalysts have high performance characteristics, including high comonomer incorporation into ethylene/olefin copolymers, where such olefins are for example, 1-octene, propylene or styrene. The catalysts particularly polymerize styrene to form polystyrene.

Phenol-heterocyclic ligands, metal complexes, and their uses as catalysts

The present invention provides a method of producing oligomers of olefins, comprising reacting olefins with a catalyst under oligomerization conditions. The catalyst can be the product of the combination of a chromium compound and a pyridyl amine or a heteroaryl-amine compound. In particular embodiments, the catalyst compound can be used to trimerize or tetramerize ethylene to 1-hexene, 1-octene, or mixtures of 1-hexene and 1-octene.
