SANS and zero-shear viscosity from a 0.1 M solution of CTAB at various concentrations (c) of NaSal are reported. The viscosity shows two pronounced maxima as a function of c. The SANS distributions for salt concentrations beyond the first viscosity maximum are significantly different from those for lower salt concentrations. In particular, analysis of the data shows that the micelle lengths for higher salt concentrations are exponentially distributed which indicates the living polymer regime.
