The decreases of the exchange micellar rate constant, determined from
stopped flow kinetic study, and of the sticky parameter, determined by
small angle X-ray scattering, with the water volume fraction are stro
ngly correlated. This phenomenon is explained according to the contact
value of the micelle-micelle correlation function and the surfactant
monolayer rigidity. It is shown that the attractive interactions gover
n the decrease of the exchange process with the increase in the number
of droplets.
