Oliver Brummer 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).

  • Patent number: 7659415
    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: July 9, 2007
    Date of Patent: February 9, 2010
    Assignee: Symyx Solutions, Inc.
    Inventors: Thomas R. Boussie, Oliver Brummer, Gary M. Diamond, Christopher Goh, Anne M. LaPointe, Margarete K. Leclerc, James A. W. Shoemaker
  • Patent number: 7563741
    Abstract: This invention relates to silicone compositions which can be crosslinked, preferably into elastomers, by hydrosilylation of at least one PolyOrganoSiloxane -A- carrying unsaturated bonds, using at least one polyorganohydrosiloxane —B— in the presence of a carbene-based metal catalyst —C— as defined in the description and which optionally comprises at least one inhibitor -D- of the hydrosilylation reaction.
    Type: Grant
