Abstract
The article presents kinetic data on micellar systems that were obtained with relaxation techniques. Problems that are relevant to the following topics are discussed in detail: Differences in the dynamic behaviour of micellar systems consisting of single‐ and double chain detergents. The dynamics of micellar systems consisting of ionic detergents with hydrophobic counterions. The dynamic behavior of micellar systems of perfluorated ionic detergents. For most of the systems two relaxation times could be observed which very often showed characteristic differences in their temperature and concentration dependence. The two relaxation processes were associated according to the theory of micelle formation by G. Aniansson and S. Wall to the shift of the micellar distribution curve and the change of the micelle concentration. The following parameters were evaluated from the data: The residence times of the detergent molecules inside the micelles, the mean aggregation number of the micelles, the width of the micellar distribution curves and the concentrations of the micellar nuclei and their aggregation numbers.
