New ligands and compositions with bridged bis-aromatic ligands are disclosed that catalyze the polymerization of monomers into polymers. These catalysts with metal centers have high performance characteristics, including higher comonomer incorporation into ethylene/olefin copolymers, where such olefins are for example, 1-octene, propylene or styrene. The catalysts also polymerize propylene into isotactic polypropylene.

Bridged bi-aromatic ligands, catalysts, processes for polymerizing and polymers therefrom

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

Methods of using heterocycle-amine ligands, compositions, complexes, and 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.

Methods of oligomerizing olefins

Copolymers of an olefin or alpha-olefin and a cyclic olefin where the cyclic olefin comprises greater than 50 mole percent by weight of the copolymer have been discovered. These copolymers have unique properties, including low density, high chemical resistance, low elongation to break, low shrinkage, good processability, low water absorption and good clarity. The copolymers also may be used as an engineering plastic. A process for making these copolymers is also disclosed, with the process comprising reaction of the olefin or alpha-olefin with the cyclic olefin under polymerization conditions including a catalyst comprising a metal-ligand complex having a bridged bi-phenyl phenol ligand structure.
