Preferred Label : polyelectrolyte network;
IUPAC definition : polymer network containing ionic or ionizable groups in a substantial fraction of
its constitutional units.;
Scope note : a polyelectrolyte network in contact with a solution of a salt is able to exchange
counter-ions (cations or anions) with ionic species in the solution and act as an
ion exchanger. therefore, a polyelectrolyte network is frequently described as an
ion-exchange polymer.; in contrast to a polyelectrolyte, a polyelectrolyte network is always insoluble, although
swelling or contraction can occur when it is immersed in a solvent.; a polyelectrolyte network is sometimes called a crosslinked polyelectrolyte. use of
the latter term is not recommended unless the polyelectrolyte network is formed by
the crosslinking of existing polyelectrolyte macromolecules rather than by non-linear
polymerisation;
