  • Patent number: 11639479
    Abstract: There is disclosed an antifoam component which includes at least one acrylamide polymer for use in a diesel fuel. Acrylamide polymers prepared by polymerizing a (meth)acrylamide monomer to yield a homopolymer or, alternatively, the acrylamide polymer may be prepared by polymerizing a (meth)acrylamide monomer and a (meth)acrylate monomer to yield a heteropolymer.
    Type: Grant
    Filed: March 19, 2019
    Date of Patent: May 2, 2023
    Assignee: The Lubrizol Corporation
    Inventors: James H. Bush, David M. Nickerson, Rochelle L. Kovach, Jayasooriya Sujith Perera, Elizabeth A. Schiferl, Kamalakumari K. Salem
  • Publication number: 20230002697
    Abstract: The disclosed technology relates to lubricants for driveline and industrial gears containing a mono-ester or a mixture of mono- and di-esters, as well as a method of lubricating driveline and industrial gears with such a lubricant.

  • Publication number: 20220259511
    Abstract: There is disclosed an antifoam component which includes at least one poly(acrylate) copolymer for use in a fuel. Poly(acrylate) polymers prepared by polymerizing a (meth)acrylate monomer comprising C1 to C30 alkyl esters of (meth)acrylic acid (“multifunctional monomer”) are also disclosed. Other poly(acrylate) polymers prepared by polymerizing (i) a (meth)acrylate monomer comprising C1to C4 alkyl esters of (meth)acrylic acid (“solubility monomer”); (ii) a (meth)acrylate monomer comprising C5 to C12 alkyl esters of (meth)acrylic acid (“surface tension monomer”); and (iii) optionally at least one additional monomer comprising a solubility monomer, a surface tension monomer, a monomer comprising C1 to C30 alkyl esters of (meth)acrylic acid (“multifunctional monomer”), or combinations thereof are also disclosed.

  • Patent number: 10975323
    Abstract: A lubricating composition includes a sulfurized oxy-substituted aromatic polyol compound and an oil of lubricating viscosity. The sulfurized oxy-substituted aromatic polyol compound includes at least one of a sulfurized oxy-substituted aromatic polyol and a salt of a sulfurized oxy-substituted aromatic polyol. The compound is suitable as a replacement for detergents that contain Cn alkyl phenols derived from oligomers of propylene.
