ABSTRACT:
Ion exchange resins are prepared by a process comprising functionalizing styrene-divinylbenzene copolymers, or other crosslinked vinyl copolymers, by sulfonation or chloromethylation and amination, and achieving high ion exchange capacity and a low degree of resin bead fragmentation, in the presence of hydrocarbon liquids, such as cyclohexane.
