• polyelectrolyte

    Polyelectrolyte

    Polyelectrolytes are polymers whose repeating units bear an electrolyte group. Polycations and polyanions are polyelectrolytes. These groups dissociate in aqueous solutions (water), making the polymers charged.Polyelectrolyte properties are thus similar to both electrolytes and polymers (high molecular weight compounds) and are sometimes called polysalts.
