between anion and cation resins. In the process, the copolymer is reacted with chloromethylmethyl ether (CME) to produce a chloromethylated copolymer intermediate. Although still nonionic and not yet an ion-exchange resin, the intermediate product is sufficiently active to react with simple amines to form anion-exchange resins.
Cation Exchange Resin – an overview | ScienceDirect Topics
In a different stabilization technique, the wines are passed over cation- or anion-exchange resins. In the exchange process, the resins become enriched with ions from the wine and vice versa. Cation-exchange resins donate protons or sodium ions according to whether the resin has been preconditioned with an acid or a sodium salt, respectively.

The resin column will filter some undissolved material, but the efficiency for filtration is usually significantly less than that for removal by ion exchange. Thus, the overall efficiency is less than in a mixed-bed resin. The capacity of ion exchange resins to remove impurity ions is given in Table 2 along with other information on resins.
