Notes:
Polymers, such as polyvinyl formal (PVF) and polyvinyl acetate (PVAc), which are insoluble in water, dissolved in anionic surfactant solution. Polymer solutions of PVF, PVAc, and polyvinyl alcohol in surfactant were studied viscometrically and electrophoretically. The polymer forms a complex with the surfactant, the behavior of which is similar to that of polyelectrolyte. The complex is negatively charged and migrates to the anode. With dialysis of the solution of polymer-surfactant complex against running water, the polymer separates out; however, the polymer does not separate out of undialyzed solution, even if the solution is diluted to far less concentration than the CMC of the surfactant. Thus the dissolution of the polymers in the surfactant solution is due to the oriented adsorption of surfactant ions on the polymer molecule. The amount of adsorbed surfactant ions was estimated. The adsorption might be of the Langumuir type.
