The present invention is directed to certain novel late transition metal salicylaldimine chelates and, further, to novel bidentate ligand compounds of substituted salicylaldimine, and their utility as polymerization catalysts alone or in combination with adjunct agent and/or Lewis base in processes of polymerizing olefin monomers and copolymerizing olefin monomers with functionalized olefin monomers.

Catalyst compositions and processes for olefin oligomerization and polymerization

A process for forming neutral late transition metal chelates useful as polymerization catalysts comprising contacting a bidentate ligand forming compound that is free of electron-withdrawing groups with a di(tertiary amine) late transition metal reagent in the presence of an inert liquid, an olefinic monomer or a polar liquid selected from nitrites, ethers, aromatic heterocyclic amines, alcohols, nitroalkanes, nitroaromatics or mixtures thereof. The process provides a solid product or a solution of a storage stable transition metal bidentate ligand containing catalyst product which remains active for an extended storage period. Alternately, the present process can be conducted in situ in a polymerization zone of olefinic polymerization.

Olefin polymerization catalysts and processes for making and using same

Non-ionic bidentate late transition metal chelates tethered to an inert support by a covalent bond group to provide a catalyst useful in slurry and gas phase polymerization of olefins.

Supported catalysts and olefin polymerization processes utilizing same

Non-ionic late transition metal chelates of salicylaldimine and pyrrolaldimine can be tethered to an inert support by a covalent bond to provide a catalyst useful in slurry and gas phase polymerization of olefins.

Substantially linear vinylene carbonate/1-olefin copolymers, a process of forming the same, and packaging materials incorporating the same are described. These copolymers are formed by reacting the component monomers in the presence of a single component, non-ionic polymerization catalyst at relatively low temperatures and pressures.
