Abstract
Thermally regenerable ion exchange resins, which are oxidation resistant, comprising polyetheramines derived from a poly (.alpha.-haloepoxyethane) which has been crosslinked and aminated.
Claims16
A thermally regenerable amphoteric ion-exchange resin comprising an acidic ion-exchange polymeric component and a basic ion-exchange polymeric component, characterized in that the basic polymeric component is a polyetheramine which is prepared from a poly(.alpha.-halo-epoxyalkane) or a copolymer thereof, by treatment with an aminating agent selected from the group consisting of methylamine, ethylamine, dimethylamine, diethylamine, methylethylamine, pyrrolidine, piperidine and homopiperidine, and a crosslinking agent which is a diamine or a salt thereof.
