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