  • Matrix amphoteric thermally regenerable ion exchange resins
    Patent number: 4229545
    Abstract: Making amphoteric thermally regenerable ion-exchange resins by encapsulating poly (weak acid) ion exchange particles in a matrix of a polymer of opposite ion-exchange type in the presence of certain agents which inhibit the formation of deleterious salts between the resins.
    Type: Grant
    Filed: February 12, 1979

  • Process for demineralizing saline solutions
    Patent number: 4206051
    Abstract: A process for demineralizing an aqueous saline solution containing a deoxygenating agent by treating it with a thermally regenerable ion-exchange resin comprising a resinous material derived from a substituted diallylamine.
    Type: Grant
    Filed: December 18, 1978
    Date of Patent: June 3, 1980

  • Amphoteric composite resins and method of preparing same by polymerization of a two-phase dispersion of monomers
    Patent number: 4134815
    Abstract: A process of manufacturing an amphoteric composite resin which process comprises first polymerizing a dispersion comprising two liquid phases wherein the first liquid phase comprises at least one monomer containing a basic group or a precursor or derivative thereof and a crosslinking agent, and the second liquid phase comprises at least one monomer containing an acidic group or a precursor or derivative thereof and a crosslinking agent, and wherein the monomers are not of opposite charge, the two liquid phases are substantially immiscible and partitioning of the monomers from one liquid phase to the other is minimal, to form a composite polymeric material; and second treating the composite polymeric material to convert any acidic group precursor or derivative and any basic group precursor or derivative to the free acid and free base respectively to form an amphoteric composite resin.
