Patents by Inventor Sergey Paramonov

Sergey Paramonov 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).

  • Polymerization of isoprene from renewable resources
    Patent number: 8901262
    Abstract: This invention relates to compositions and methods for producing polymers of isoprene derived from renewable resources, such as isoprene produced from cultured cells that use renewable carbon sources. A starting isoprene composition, such as a bioisoprene composition, is distinguished from petroleum based isoprene by its purity profile (such as lower levels of certain C5 hydrocarbons other than isoprene, presence of certain compounds associated with the biological process for production) and the relative content of the carbon isotopes. Polymers obtained by polymerization of such starting isoprene composition according to this invention, such as a polyisoprene homopolymer or a copolymer having repeat units that are derived from isoprene, are distinguishable from isoprene containing polymers from petrochemical resources.
    Type: Grant
    Filed: August 20, 2013
    Date of Patent: December 2, 2014
    Assignees: The Goodyear Tire & Rubber Company, Danisco US Inc.
    Inventors: Joseph C. McAuliffe, Sergey Paramonov, Stephan Rodewald, Karl J. Sanford
