The polymer-surfactant interaction has been treated as formation of micelle-like aggregates involving also a fragment of the polymer chain. The model adequately explains the shape of binding isotherms of ionic surfactants by polymers, the critical surfactant concentration of interaction and its dependence on polymer concentration as well as the appearance of two break-points in the colligative properties vs. surfactant concentration curves. It has been concluded from potentiometric dodecyl sulfate activity measurements that the amount of surfactant in complex increases with the equilibrium surfactant concentration until it reaches the critical micelle formation concentration. The intrinsic viscosities were determined by dilution at constant polymer-NaDS complex composition.
