  • Powder coating resin process
    Patent number: 3980733
    Abstract: A curable powder resin composition comprising an aminoplast and a polyester or polyacrylic resin. The aminoplast is a condensate of a methylolurea or methylolaminotriazine with an aliphatic alcohol and a reactive compound containing at least one reactive group selected from the group consisting of hydroxyl and amide.
    Type: Grant
    Filed: October 4, 1974
    Date of Patent: September 14, 1976
    Assignee: Monsanto Company
    Inventors: Robert A. Isaksen, Frederic J. Locke, John L. Smith, George T. Spitz
  • Process of manufacture of dielectric recording media
    Patent number: 3973055
    Abstract: The dielectric recording media comprise electroconductive substrates coated with dielectric resin binder. The process comprises dispersing an organophilic clay pigment in the dielectric resin binder and coating the electroconductive substrate with the dispersion. The organophilic clay pigment is obtained by treating calcined kaolin clay with an organotitanium compound.
    Type: Grant
    Filed: January 27, 1975
    Date of Patent: August 3, 1976

    Inventors: Albert H. Markhart, David R. Cahill
  • Anti-migratory additive for emulsified phenolic resin systems
    Patent number: 3973070
    Abstract: The present invention relates to an anti-migratory (as respects impregnated porous sheet members) phenol-formaldehyde resole resin in water emulsions. The emulsion is rendered anti-migratory (when impregnated into paper) through the addition thereto of an anti-migratory agent selected from the group consisting of polyelectrolytes, certain salts of inorganic acids, and combinations thereof. The composition is especially useful in the impregnation of filter paper.

    Inventor: Woodrow Hayes Ingram, II
  • Process for recovery and reuse of textile size
    Patent number: 3960485
    Abstract: Warp textile sizes comprising interpolymers of vinyl esters are recovered by extraction of the interpolymer from woven cloth with an aqueous solvent to form an aqueous solution of the interpolymer. The interpolymmer is precipitated from the aqueous solution by adjusting the alkali metal ion concentration of the solution within defined limits and adding acid to reduce the pH to the range of 1 to 3. The precipitated polymer is isolated from the supernatant solution and is reused by dissolving it in an aqueous base to yield a sizing solution.
    Type: Grant
    Filed: June 19, 1974
    Date of Patent: June 1, 1976
    Assignee: Monsanto Company
    Inventors: Joel Fantl, Joseph G. Martins
  • Dielectric coating compositions
    Patent number: 3951882
    Abstract: A dielectric coating composition comprising an organophilic clay pigment dispersed in a dielectric resin binder. The organophilic clay binder is prepared by treatment of a kaolin clay with an organotitanium compound. Preferred binders include styrene interpolymers and poly(vinyl butyrals).
    Type: Grant

    Inventors: Albert H. Markhart, David R. Cahill
  • Backing sheet coated with catalyst and self curing interpolymer adhesive
    Patent number: 3931444
    Abstract: Pressure-sensitive resin solutions containing an acid-epoxy self-curing interpolymer and 1,3-bis(dimethylamino)-2-hydroxypropane. The solutions exhibit improved viscosity stability and provide pressure-sensitive resin films with cohesive strength and low release values from silicone release paper.
