    Abstract: A zwitterionic Group VIII transition metal complex containing the simple and relatively small 3-(arylimino)-but-1-en-2-olato ligand that catalyzes the formation of polypropylene and high molecular weight polyethylene. A novel feature of this catalyst is that the active species is stabilized by a chelated olefin adduct. The present invention also provides methods of polymerizing olefin monomers using zwitterionic catalysts, particularly polypropylene and high molecular weight polyethylene.

  • Patent number: 7998895
    Abstract: Transition metal complexes of selected monoanionic phosphine ligands, which also contain a selected Group 15 or 16 (IUPAC) element and which are coordinated to a Group 3 to 11 (IUPAC) transition metal or a lanthanide metal, are polymerization catalysts for the (co)polymerization of olefins such as ethylene and ?-olefins, and the copolymerization of such olefins with polar group-containing olefins. These and other nickel complexes of neutral and monoanionic bidentate ligands copolymerize ethylene and polar comonomers, especially acrylates, at relatively high ethylene pressures and surprisingly high temperatures, and give good incorporation of the polar comonomers and good polymer productivity. These copolymers are often unique structures, which are described.

  • Publication number: 20100305350
    Abstract: A diamidine compound is used to complex to a catalytic metal atom. This can be dissolved in an organic solution for homogenous catalytic reactions, such as a hydrogenation, polymerization reaction. The metal complex can be separated from the reactant solution after the reaction by bubbling carbon dioxide through the solution causing the formation of diamidinium bicarbonate, which is insoluble in organic solution and can be recovered in an aqueous medium. The diamidinium bicarbonate can be further converted back into an organic soluble diamidine by bubbling the aqueous solution with argon or nitrogen, permitting the reuse of the catalyst in homogeneous catalytic reactions.
