polyelectrolyte network

@[email protected] containing ionic or ionizable groups in a substantial fraction of its constitutional units.
  1. A @[email protected] @[email protected] is sometimes called a crosslinked @[email protected] Use of the latter term is not recommended unless the @[email protected] @[email protected] is formed by the @[email protected] of existing @[email protected] macromolecules rather than by non-linear polymerisation.
  2. In contrast to a @[email protected], a @[email protected] @[email protected] is always insoluble, although swelling or contraction can occur when it is immersed in a solvent.
  3. A @[email protected] @[email protected] in contact with a solution of a @[email protected] is able to exchange @[email protected] (cations or anions) with ionic species in the solution and act as an @[email protected] Therefore, a @[email protected] @[email protected] is frequently described as an @[email protected]
