  • Radiation-curable compositions comprising isocyanuric acid-acrolein derivatives
    Patent number: 4555319
    Abstract: Radiation-curable compositions comprising an ester of an ethylenically unsaturated acid and a polyhydric alcohol and an oxopropyl isocyanurate formed by the addition of from 2 to 3 moles of acrolein to 1 mole of isocyanuric acid. The compositions are useful as coatings, printing inks, adhesives and the like.

    Inventors: Saul M. Cohen, John R. LeBlanc
  • Polymer compositions comprising hemiacetals of adducts of acrolein and isocyanuric acid
    Patent number: 4374240
    Abstract: Polymer compositions comprising hemiacetals of acrolein-isocyanuric acid adducts and polyfunctional compounds containing hemiacetal-reactive groups such as amines, amides, alcohols, thiols and oxiranes. The compositions are useful in molding, laminating, coating and adhesive applications.
    Type: Grant
    Filed: December 22, 1980

    Assignee: Monsanto Company
    Inventors: Saul M. Cohen, John R. LeBlanc
  • Adducts of acrolein and isocyanuric acid
    Patent number: 4326057
    Abstract: 3-Oxopropyl isocyanurate compositions are prepared by addition of acrolein to isocyanuric acid. Reaction of the 3-oxopropyl isocyanurate compositions with alcohols yields hemiacetals and acetals. The compositions and their hemiacetals and acetals are useful polymerizing or crosslinking agents for polyfunctional compounds containing aldehyde-reactive groups.
    Type: Grant
    Filed: December 22, 1980
    Date of Patent: April 20, 1982
    Assignee: Monsanto Company
    Inventors: Saul M. Cohen, John R. LeBlanc
  • Acetals of adducts of acrolein and isocyanuric acid
    Patent number: 4321375
    Abstract: Acetals are prepared by reacting monohydric primary or secondary alcohols with acrolein-isocyanuric acid adducts. The acetals are useful polymerizing and cross-linking agents for polyfunctional compounds containing acetal-reactive groups such as alcohols, thiols, oxiranes and amides.
