The structure of micelles formed by the cationic surfactant erucyl bis(hydroxyethyl)methylammonium chloride in mixtures with oppositely charged rigid-chain polyelectrolyte xanthan in the presence of a salt is studied by small-angle neutron scattering. It is shown that both in the absence and in the presence of a polymer, micelles have a cylindrical shape, and their cross-sectional radius does not change with the addition of different polymer concentrations up to 0.45 wt %. The lack of interaction between surfactant micelles and polymer due to screening of the electrostatic interaction leads to the formation of two interpenetrating networks, one of which is formed by intertwined wormlike surfactant micelles; the other, by polymer molecules.
