Jennifer HOLTZINGER 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).

  • Comb polymers comprising imide functionality
    Patent number: 11072677
    Abstract: Selected comb polymers include specified amounts of macromonomer and imide functionalization. Further, a method is useful for the preparation of such comb polymers. Lubricant compositions including such comb polymers are useful for reducing wear and fuel consumption of lubricant compositions, especially of engine oil (EO) compositions.
    Type: Grant
    Filed: July 12, 2018
    Date of Patent: July 27, 2021
    Assignee: Evonik Operations GmbH
    Inventors: Katrin Schöller, Jennifer Holtzinger, Fabian Ziegler, Klaus Schimossek, Frank Lauterwasser
  • Polymeric-inorganic particles useful as lubricant additives
    Patent number: 10954466
    Abstract: The invention relates to polymeric-inorganic nanoparticles and preparation processes thereof. The invention also relates to a powder, concentrate and lubricating composition comprising these polymeric-inorganic nanoparticles, to a method of dispersing nanoparticles in lubricating oil, as well as the use of these polymeric-inorganic particles in an oil lubricant formulation to reduce pour point, friction and wear.

  • LUBRICANT COMPOSITION WITH AN IMPROVED VISCOSITY CHARACTERISTIC AT LOW OPERATING TEMPERATURE
    Publication number: 20190300808
    Abstract: A lubricant composition with a comb polymer and a synthetic base oil has improved viscosity characteristics at low operating temperatures. In addition, a comb polymer can be used for producing a lubricant having an R-factor of less than or equal to 8, wherein the R-factor is defined as the ratio of the kinematic viscosity at ?20° C. and the kinematic viscosity at +20° C.
