Using the surfactant C14EO8 we demonstrate how the effect of micellar kinetics on the dynamic properties of adsorption layers can be experimentally studied. The simplest theoretical models are applied, however, a rather good agreement with the experimental data is observed. In adsorption dynamics from solutions far above the CMC we observe adsorption rates which cannot be explained by usual micelle formation constants kf. For the relaxation behaviour (at low frequencies) no peculiarities are observed, i.e. the frequency behaviour of the viscoelasticity modulus can be understood by using effective diffusion coefficient of monomers proposed by the model of Joos.
