  • Polyacrylamide antifoam components for use in diesel fuels
    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
  • POLYACRYLATE ANTIFOAM COMPONENTS FOR USE IN FUELS
    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.
