  • DISPERSANT VISCOSITY MODIFIERS WITH AMINE FUNCTIONALITY
    Publication number: 20190112542
    Abstract: A lubricating composition includes an oil of lubricating viscosity and an oil-soluble dispersant viscosity modifier. The dispersant viscosity modifier includes an olefin-based polymer backbone and at least one pendent group derived from a functionalized aliphatic amine. Each pendent group is independently attached to the olefin-based polymer backbone. The pendent group is non-ionic, non-basic, and non-acidic and includes a functional group which includes at least one heteroatom other than nitrogen.
    Type: Application
    Filed: December 10, 2018
    Publication date: April 18, 2019
    Applicant: The Lubrizol Corporation
    Inventors: ADAM PRESTON, Yanshi Zhang, Sona S. Slocum, Matthew .D. Gieselman
  • DISPERSANT VISCOSITY MODIFIERS WITH SULFONATE FUNCTIONALITY
    Publication number: 20170283733
    Abstract: A lubricating composition includes an oil of lubricating viscosity and an oil-soluble dispersant viscosity modifier, which includes an olefin-based polymer backbone and at least one pendent functional group. Each of the at least one pendent functional group is independently attached to the olefin-based polymer backbone by a linking group. The at least one pendent functional group includes a sulfonate moiety.
