  • Patent number: 9399614
    Abstract: Conjugated diene acids and derivatives thereof, are disclosed herein. In some embodiments, the conjugated diene acids and derivatives thereof are derived from the metathesis of a natural oil followed by isomerization. Uses of conjugated diene acids and derivatives thereof in various compositions are also disclosed herein.
    Type: Grant
    Filed: July 14, 2015
    Date of Patent: July 26, 2016
    Assignee: Elevance Renewable Sciences, Inc.
    Inventors: Ryan Littich, Charles Coburn
  • Publication number: 20160032167
    Abstract: Compositions useful as wellbore fluids are generally disclosed. In some embodiments, the compositions include polymerizable olefinic surfactant compositions, which, under certain conditions, can polymerize via free-radical polymerization to form surfactant polymers. In some embodiments, the compositions are introduced to an oil well as part of the drilling or extraction process, e.g., to assist in flushing hydrocarbon material out of subterranean formations.

  • Publication number: 20150197683
    Abstract: Compositions for treating high-molecular-weight components of a petroleum fluid are generally disclosed. In some embodiments, such compositions include olefinic ester compounds, such as alkyl esters of C10-18 unsaturated fatty acids. In some embodiments, such compositions are added to a petroleum fluid to improve the rheological properties, e.g., breaking up or inhibiting the precipitation of high-molecular-weight components of petroleum fluids. In some other embodiments, such compositions are used for removing deposits of such high-molecular-weight components from the surfaces of equipment used for extracting or transporting petroleum or natural gas.

  • Patent number: 5470908
    Abstract: Described herein is a composition comprising at least 10 percent by weight of water and, based on the weight of components (a), (b), and (c); (a) 0 to about 95 percent by weight of a water-compatible polymer having at least two pendant carboxylate groups; (b) 1 to about 60 percent by weight of a polymeric polycarboxylate polymer different from (a) having (1) at least two pendant carboxylate groups and (2) at least one internal amide, thioamide, urea, thiourea, biuret, dithiobiuret, or urethane group; and (c) 2 to about 70 percent by weight of a polyfunctional crosslinking agent having an ionic or potentially ionic moiety counter ion capable of reacting with the carboxylate groups of (a) and (b). Component (b) may also contain fluoroalkyl groups. The composition of the invention provides a water-based coating which, when deposited on a surface to be coated and allowed to dry and form a crosslinked polymer, has a high degree of wear resistance, hardness, and impact resistance.
