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. |
