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.
