  • Publication number: 20040075079
    Abstract: The invention relates to compositions comprising an ester of a polyol and a mixture of fatty acids, wherein at least a part (I) of the esterified fatty acids has a chain length of 5-12 carbon atoms and another part (II) of the esterified fatty acids has a chain length of 16-22 carbon atoms, and wherein the composition has a viscosity of 7000 mm 2 /s or less, when tested according to ASTM (D2531). Such compositions have unexpected good low temperature properties, in particular a good rheology after having been kept for a prolonged time at a low temperature (e.g. at −30° C.). These compositions are suitable for use as (part of) hydraulic fluid in applications at low temperatures.

  • Patent number: 4004060
    Abstract: This invention provides certain complex molecules which possess excellent solubility in water and excellent reactivity making them useful in the manufacture of non-woven products and processes for their preparation. The compositions are comprised of structural units derived from a higher polycarboxylic acid and about one mole of a di-epoxide per carboxyl group, about 0.5 to 1.5 moles of an alkoxy polyoxyalkylene compound and about 0.5 to 1.5 moles of an alkanolamine neutralized with a lower monocarboxylic acid.
    Type: Grant

    Date of Patent: January 18, 1977
    Assignee: Emery Industries, Inc.
    Inventors: Arie Dick Kardol, Johannes Helmond
  • Patent number: 3959187
    Abstract: Improved water-emulsifiable ester lubricants for polymeric and metal materials are provided which yield stable emulsions even in the absence of emulsifying agents. The ester lubricants are obtainable from a higher molecular weight di- or polycarboxylic acid and a polyalkoxylated lower alkyl alcohol.
