  • Filled polyol component viscosity reduction
    Patent number: 6313207
    Abstract: The disclosed invention relates to filled polyol compositions which employ midrange molecular weight polyols and which have specific gravities less than about 1.5 and viscosities less than about 100,000 centipoise at 25 C. The filled polyols are especially suited for manufacture of filled polyurethane compositions.
    Type: Grant

    Inventor: David R. Macfarland
  • Preparation of noncellular polyurethane compositions
    Patent number: 4288587
    Abstract: Noncellular polyurethane compositions are prepared by reacting an organic polyisocyanate with select chlorine-containing polyols in the presence of a catalytic amount of a metal carboxylate compound. These reactions produce noncellular polyurethanes which are useful as coatings and castings.
    Type: Grant
    Filed: May 5, 1980
    Date of Patent: September 8, 1981
    Assignee: Olin Corporation
    Inventors: Richard J. Turley, David R. MacFarland
