  • Method for making a storage stable blend of a long chain polyol and a short chain diol by incorporating a phenyl therein and the resulting blend
    Patent number: 4786435
    Abstract: Disclosed is a storage stable blend of a long chain polyol and a short chain diol wherein the diol is present in an amount whereby the diol and polyol form an incompatible blend. The blend is rendered storage stable by the addition of a compatibilizing amount of a phenol.
    Type: Grant
    Filed: April 10, 1987
    Date of Patent: November 22, 1988
    Assignee: Ashland Oil, Inc.
    Inventor: Timothy A. Tufts
  • Thermosetting molding compounds
    Patent number: 4758400
    Abstract: Fiber reinforced molding compounds wherein the resinous matrix is a thermosetting linear polymer characterized in constituting two oligomeric ethylenically unsaturated polyester segments joined through a polyurethane residue and having acryloyl or methacryloyl end groups.
    Type: Grant
    Filed: January 27, 1987
    Date of Patent: July 19, 1988
    Assignee: Ashland Oil, Inc.
    Inventors: William R. Dunnavant, Gilbert M. Gynn, Richard E. Field
  • Thermoset polymer compositions
    Patent number: 4757115
    Abstract: Thermoset polymers are prepared by reacting an ethylenically unsaturated resin monomer and a bicyclic amide acetal with a polyisocyanate in the absence or presence of a vinyl monomer. Reaction rates are suitable for effecting RIM processing. The resultant polymers exhibit improved impact resistance. Further variation in physical properties can be achieved through the use of a diol chain extender for the polyisocyanate.

  • Storage stable polyol compositions
    Patent number: 4755321
    Abstract: Disclosed is a storage stable blend of a long chain polyol and a short chain glycol wherein the glycol is present in an amount whereby the glycol and polyol form an incompatible blend. The blend is rendered storage stable by the addition of a compatibilizing amount of a salt wherein the salt is formed from a metal having a charge density of from about 1.25 to about 1.45.

  • Pressure sensitive adhesive reaction product of bicyclic amide acetal and acrylate interpolymer
    Patent number: 4677167
    Abstract: Curing of a pressure-sensitive adhesive resin based on an acrylic interpolymer containing pendent carboxylic acid or anhydride groups is effected through reaction with a bicyclic amide acetal cross-linking agent. The cross-linked resins exhibit a high degree of relatively permanent cohesive strength.
    Type: Grant

    Assignee: Ashland Oil, Inc.
    Inventor: Anil B. Goel
  • Method for preparing laminated articles
    Patent number: 4618390
    Abstract: A method of bonding a flexible substrate; e.g., vinyl, cloth, paper, etc., to a rigid wood substrate. The method comprises consolidating the two substrates through the medium of a curable adhesive composition consisting essentially of an aqueous emulsion of a butyl acrylate-methyl methacrylate-2-hydroxyethyl acrylate terpolymer adjusted to pH 9 to pH 10 with 2-amino-2-methyl-propanol, polypropylene glycol, an acrylamide-acrylic acid copolymer thickener, containing a dispersed polyisocyanate hardening agent. Decorative vinyl/wood laminates for use in mobile home construction can be advantageously prepared in this manner.
