  • High solids ethylene acrylic acid aqueous dispersions and methods of producing same
    Patent number: 5591806
    Abstract: A uniquely treated bead of ethylene acrylic acid (EAA) capable of forming a high solids aqueous dispersion in excess of 38% solids wherein the EAA may be prepared by either batch or continuous processes wherein the EAA is substantially fully reacted with ammonia, sodium or potassium in little or substantial absence of water, followed by a separate aqueous dispersion step, resulting in a unique and quick-drying dispersion material highly useful in coating, adhesive, laminating, ink and similar processes, and wherein operating expense and environmental concerns are at a minimum as a consequence thereof.The treated EAA may be prepared in a substantially dry to merely moist state for incorporation into an aqueous dispersion with high percentages of EAA having either higher or lower molecular weight with low viscosities as compared to heretofore.
    Type: Grant
    Filed: June 7, 1995
    Date of Patent: January 7, 1997
    Assignee: Dominion Chemical Company
    Inventors: Frank P. Recchia, Wilson M. Ferrell, W. Maclin Ferrell, Jr.
