  • US Patent:
    20020156316, Oct 24, 2002
  • Filed:
    Apr 17, 2002
  • Appl. No.:
    09/996480
  • Inventors:
    Indulis Gruzins - Louisville KY,
    Donald McElheney - Louisville KY,
    Robert Hire - Dayville CT,
    Jerry Necessary - Elizabethtown KY,
    Joseph Farrell - Brandenburg KY,
  • International Classification:
    C07C069/80
    C07C069/40
    C07C069/52
  • US Classification:
    560/076000, 560/198000
  • Abstract:
    The present invention is directed to a low viscosity carboxyl-containing polyol composition having a viscosity in the range of about 3,000-100,000 centipoise, and having an oligomer content of less than 30 mg KOH/g. Preferably, the carboxyl-containing polyol has one ester group per molecule. The carboxyl-containing polyol is suitable for use in preparing low viscosity polyurethane prepolymers. Also disclosed is a method of producing this carboxyl-containing polyol composition by reacting a low molecular weight triol with an acid anhydride in the presence of 25-500 ppm of an inorganic or organic acid catalyst. The organic or inorganic acid is preferably selected from the group consisting of hydrochloric acid, sulfuric acid, nitric acid, formic acid, proprionic acid, p-toluenesulfonic acid, oxalic acid, and combinations thereof. The present invention is also directed to methods of making the above carboxyl-containing polyols, as well as prepolymers and urethane polymers containing the above carboxyl-containing polyols.

  • Abstract:
    The present invention is directed to carboxyl-containing monomers for use in preparing a polyurethane polymers, the carboxyl-containing monomers being the reaction product of a low molecular weight polyol compound and an acid anhydride in the presence of 5-500 ppm phosphoric acid, the carboxyl-containing monomer having a viscosity in the range of 3,000 to 100,000 centipoise, and having oligomer content of less than about 30 mg KOH/g. The present invention is also directed to methods of making the above carboxyl-containing monomers, as well as prepolymers and urethane polymers containing the above carboxyl-containing monomers.
