      abstract     = {This work discusses the polyelectrolyte sodium hyaluronate
                      (HA) and its polyelectrolyte/surfactant complexes (PESCs)
                      with tetradecyltrimethylammonium bromide (TTAB) in the
                      semi-dilute regime of HA and at high concentrations of TTAB.
                      The structure and flow properties in the surfactant excess
                      region were studied by light scattering and small angle
                      neutron scattering (SANS) as well as by rheology. The unique
                      behaviour of HA to maintain its high viscosity was observed
                      even at very high TTAB concentrations of 496 mM and this
                      effect was systematically studied in the concentration range
                      from 1 to 25 mM HA. From the data, it could be concluded
                      that: (1) extended rod-like structures of the PESCs prevent
                      molecular dissolution of HA by TTAB. (2) HA and TTAB
                      micelles interact rather weakly as seen by a low fraction of
                      bound micelles. (3) At very high TTAB concentrations a
                      decompaction of PESCs (fractal dimension Df going from 2.0
                      to 1.2) occurs with increasing HA concentration but (4) both
                      the entanglement of HA and the structure of the micelles are
                      not affected.},
