Paper Abstract

The stability of non-stoichiometric interpolyelectrolyte complexes (IPECs), which contain relatively long poly(methacrylate anion)s and relatively short poly(N-ethyl-4-vinylpyridinium cation)s, with respect to their dissociation into constituent polyelectrolytes in water-salt media was studied by fluorescence quenching and velocity sedimentation techniques. The dissociation of IPECs was found to begin at a certain critical salt concentration and to proceed by a gradual release of polycations from IPECs. The effects of polyion chain length and polyion charge density on the stability of IPECs were examined.
