  • N-Cyano amide compositions and adducts thereof
    Patent number: 4435549
    Abstract: This invention relates to novel N-cyano amide compositions and adducts thereof of the formula ##STR1## wherein R is a simple organic moiety or a polymeric adduct with the valence of n and n is 2 or 3. The composition, per se, can be used as a curing agent for epoxy resins to form a thermoset material on heating.
    Type: Grant

    Inventor: Shiow-Ching Lin
  • Curable N-acylurea polymers and coating compositions therefrom
    Patent number: 4328138
    Abstract: Curable N-acylurea polymers and coating compositions are provided which cure by reaction of ethylenic unsaturation of the acyl group. The subject polymers are prepared by reaction of a polymeric carbodiimide with an ethylenically unsaturated monocarboxylic acid. Coating compositions so provided may have N-acylurea polymer solids contents of about 30% to about 95% by weight, exclusive of pigment.
    Type: Grant

  • Polyazlactone-electron deficient ethylenically unsaturated resinous compositions and method for foaming same
    Patent number: 4266040
    Abstract: A reaction product of (1) resin containing a plurality of electron deficient ethylenically unsaturated groups and (2) a polyazlactone. The product may be formed without the liberation of a gas and cured at a higher temperature with the liberation of a gas to thereby form foamed product.
