ion-exchange polymer

Also contains definition of: ion-exchange membrane

Polymer that is able to exchange ions (cations or anions) with ionic components in solution.
Notes:
  1. See also: ion exchange.
  2. An ion-exchange polymer in ionized form may also be referred to as a polyanion or a polycation.
  3. Synthetic ion-exchange organic polymers are often network polyelectrolytes.
  4. A membrane having ion-exchange groups is called an ion-exchange membrane.
  5. Use of the term 'ion-exchange resin' for 'ion-exchange polymer' is strongly discouraged.
