NANOSECOND RELAXATION PROCESSES AND BROWN IAN-MOTION OF WATER-SOLUBLEPOLYMERS IN MICELLAR SYSTEMS OF SURFACE-ACTIVE COMPOUNDS IN ORGANIC-SOLVENTS

Nanosecond dynamics of hydrated reversed surfactant micelles in organi c solvents and its variation resulting from solubilization of water-so luble polymers and proteins in this micellar system were studied by po larized luminescence. The relaxation spectrum of such a system reveale d the high-frequency and the low-frequency relaxation processes. The h igh-frequency motion in the hydrocarbon medium of the micellar system was associated with the mobility of individual surfactant molecules. T he contribution due to that mobility increased with an increase in the degree of hydration of the micelles. When a polymer was incorporated into the micellar system, the transfer of macromolecules coupled to mi cellar fragments was observed in the hydrocarbon medium. This kind of motion was observed at low degrees of hydration of the micelles, and i t became less significant as the content of water in the system increa sed.
