  • Method and apparatus for treating open-weave substrates with foam
    Patent number: 4343835
    Abstract: Method and apparatus for applying foam to an open-weave substrate. The apparatus contains angled shear strips to shear the foam positioned above a foam outlet. The shear strips, enclosed at each end, define a chamber above the foam outlet having open top and bottom sides for sequential contact of both sides of the substrate with the foam as the substrate travels across the outlet and both open top and bottom sides of the chamber.
    Type: Grant

    Assignee: Union Carbide Corporation
    Inventors: Allen P. Jones, Charles J. Cunningham
  • Process for producing shaped polyurethane hydrogel articles
    Patent number: 4209605
    Abstract: Continuous process for producing hydrogels by charging preselected feeds containing poly(oxyalkylene) polyols, organic diisocyanate and catalyst to a reaction zone followed by crosslinking by exposure to atmospheric humidity. Solvents are not used and the hydrogels are shaped in desired configuration as they exit the extruder.

  • Polyurethane hydrogels having enhanced wetting rates
    Patent number: 4182827
    Abstract: The wetting rates of polyurethane hydrogels comprising lightly crosslinked polymers of isocyanate terminated prepolymers which are the reaction product of (i) poly(alkyleneoxy) polyols with (ii) organic diisocyanates that has been lightly crosslinked with (iii) water or an organic polyamine are enhanced by treating the surface of the solid hydrogel with certain ketones, alcohols, organic amines, aromatic hydrocarbons or aqueous alkali metal hydroxide solutions.
