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.

Matrix amphoteric thermally regenerable ion exchange resins

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.

Process for demineralizing saline solutions

Ion exchange resins of the poly(allylamine) type which comprise an aralkyl radical or a saturated aliphatic radical, and which may be made by reacting an allylamine type polymer with an organic dihalo compound so as to crosslink it.

Ion exchange products and processes using crosslinked allylamine

A method of manufacturing amphoteric resins. Polymeric beads are treated sequentially with two reagents of opposite acid/base character. The resins are useful in the desalination of water.
