Amphoteric ion exchange resins |
| abstract |
ABSTRACT A process for making a thermally reversible amphoteric ion exchange resin suitable for use in the demineralization of water which process comprises dis-persing particles of an ion exchange resin comprising either weakly basic or weakly acidic ionogenic groups in a solution comprising one or more monomers containing an ionogenic group, or organic precursor thereof, of opposite acid-base character to the ionogenic groups of the ion exchange resin particles, a crosslinking agent comprising two or more vinylic or allylic groups, and a porogen; secondly polymerizing the monomer to give a macroporous crosslinked polymer matrix; and thirdly treating the polymeric composition to convert any organic precursors to ionogenic groups to form an amphoteric ion exchange resin. |
