Formation of polyelectrolyte complexes in an organic solvent

Résumé

The formation of complexes of polyelectrolytes has been investigated with low charged polyelectrolytes soluble in an organic solvent. The degree of complexation has been determined from conductimetric experiments; it is independent of the degree of quaternization of the polycation but decreases as the polymer concentration and the ionic content increase. A change in the conductimetric and in the viscometric curves during addition of polycation to the polyanion (or the reverse) has been found in the range of the ionic stoichiometry. The complex formation corresponds to an electrostatic cross-link the stability of which decreases with the ionic content of the solution. © 1981.
