Abstract
It has been observed that a swollen L-alpha phase (Surfactant: Cetylpy ridinium Chloride; Cosurfactant: Hexanol; Solvent: Brine) keeps (at le ast) metastable under the addition of a Dilute quantity of a neutral, flexible polymer (Polyacrylamide) in brine in a large domain of concen tration (Ref. 3a), however the periodicity of the lamellar phase suffe rs a strong decrease. We explain this phenomenon by a privileged swell ing of the polymer coils, under the effect of an osmotic pressure loca lized in the coil region.
