Phase behavior of an ionic surfactant with mixed monovalent/polymeric counterions
Article Abstract:
The simplest possible mixtures, with a reduced number of components, compared to conventional polyelectrolyte-surfactant mixtures, were used to study the factors that control the structure and water solubility of aggregates of oppositely charged polymers and surfactants. The study confirmed that the identity of the simple monovalent counterion might be important for the structure and solubility of surfactant aggregates with mixed polymeric and simple counterions.

Phase behavior of polyion-surfactant ion complex salts: Effects of surfactant chain length and polyion length
Article Abstract:
The aqueous phase behavior of a series of complex salts, containing cationic surfactants with polymeric counterions is investigated by visual inspection and small-angle X-ray scattering. The investigated set of complex salts, involving five different surfactant chain lengths and two polyion lengths is shown to confirm to a consistent picture.

Molecular self-diffusion in micellar and discrete cubic phases of a surfactant with mixed monovalent/polymeric counterions
Article Abstract:
The molecular self-diffusion in concentrated aqueous mixtures based on an oppositely charged polymer-surfactant pair is studied by NMR pulsed field gradient techniques. It is reported that it is now possible to measure the diffusion coefficients of all molecular species over the entire composition range of monovalent/polymeric counterions.
