摘要：

Supramolecular order is established in dilute solutions of ionic polymers in the absence of salt or at low ionic strengths. This order is confirmed by the observation of a peak in light or neutron scattering and corresponds to the existence of an ordered phase. When a concentrated polyelectrolyte solution is diluted, a peak is also observed in the reduced viscosity. This behaviour could be attributed to a local transition from anisotropic to isotropic phase as a first hypothesis. The roles of the charge parameter and salt content are discussed.
