Oliver Bruemmer has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Bridged bi-aromatic ligands, catalysts, processes for polymerizing and polymers therefrom
    Patent number: 7241715
    Abstract: New ligands and compositions with bridged bis-aromatic ligands are disclosed that catalyze the polymerization of monomers into polymers. These catalysts with metal centers have high performance characteristics, including higher comonomer incorporation into ethylene/olefin copolymers, where such olefins are for example, 1-octene, propylene or styrene. The catalysts also polymerize propylene into isotactic polypropylene.
    Type: Grant
    Filed: May 16, 2006
    Date of Patent: July 10, 2007
    Assignee: Symyx Technologies, Inc.
    Inventors: Thomas R. Boussie, Oliver Brümmer, Gary M. Diamond, Christopher Goh, Anne M. LaPointe, Margarete K. Leclerc, James A. W. Shoemaker
  • Bridged bi-aromatic catalysts, complexes, and methods of using the same
    Patent number: 7241714
    Abstract: Ligands, compositions, metal-ligand complexes and arrays with substituted bridged bis-biaromatic ligands, and methods of making and using the same, are disclosed that are useful in the catalysis of transformations such as the polymerization of monomers into polymers. The catalysts have high performance characteristics, including higher comonomer incorporation into ethylene/olefin copolymers, where such olefins are for example, 1-octene, propylene or styrene. The catalysts also polymerize propylene into isotactic polypropylene.

  • Styrene polymers and phenol-triazole type complexes, catalysts, and processes for polymerizing
    Patent number: 7074870
    Abstract: Metal-ligand complexes that are useful as precursors to catalysts for the polymerization of olefins are provided. Certain of the catalysts are particularly effective at polymerizing ethylene and styrene into copolymers having novel properties, including a low molecular weight and close comparison between vinyl and methyl end groups.
