Abstract: Disclosed herein are compounds and processes useful for the oligomerization and polymerization of olefins. Transition metal catalyst complexes of groups 7 through 10 with tridentate ligands are described, along with a representative polymerization of ethylene using one of the cobalt complexes. The transition metal complexes of the invention may also be attached to a solid support and used in gas phase processes.

Abstract: The present invention provides catalyst systems useful in the polymerization of olefins comprising a transition metal component and a ligand component comprising a Nitrogen atom and/or functional groups comprising a Nitrogen atom, generally in the form of an imine functional group. In certain embodiments, the ligand component may further comprise a phosphorous atom. Preferred ligand components are bidentate (bind to the transition metal at two or more sites) and include a nitrogen-transition metal bond. The transition metal-ligand complex is generally cationic and associated with a weakly coordinating anion. In a preferred embodiment, the catalyst system of the present invention further comprises a Lewis or Bronsted acid complexed with the ligand component of the transition metal-ligand complex.

Abstract: Provided are novel olefin polymerization catalysts based on neutral nickel complexes of bidentate ligands containing a nitrogen atom and an oxygen atom and a process for the preparation of polyolefins using such catalysts. Preferred ligands possess imine and carboxylate groups.

Abstract: This invention is directed to novel Group 8-10 transition metal catalysts and to batch or continuous polymerizations using these catalysts. The catalysts of the present invention readily convert ethylene and .alpha.-olefins to high molecular weight polymers, and allow for olefin polymerizations under various conditions, including ambient temperature and pressure, and in solution. Preferred catalysts are group 8-10 transition metals having certain dipyridyl ligands bonded thereto.

Abstract: Methods for preparing olefin polymers, and catalysts for preparing olefin polymers are disclosed. The polymers can be prepared by contacting the corresponding monomers with a Group 8-10 transition metal catalyst. The polymers are suitable for processing in conventional extrusion processes, and can be formed into high barrier sheets or films, or low molecular weight resins for use in synthetic waxes in wax coatings or as emulsions.

Abstract: Homopolymers of olefin monomers having polar functional groups, and copolymers of these monomers with each other and with non-polar olefins and optionally carbon monoxide are disclosed. The polymers can be prepared by contacting the corresponding monomers with a transition metal catalyst under comparatively mild conditions; this preserves at least some of the polar functional groups in the resulting polymer. The polymers are suitable for processing in conventional extrusion processes, and can be formed into high barrier sheets or films, or low molecular weight resins for use in synthetic waxes in wax coatings or as emulsions.
