摘要：

This paper concerns mainly the effect of the shear rate on the reduced viscosity of sodium poly(styrene sulphonate) (Na PSS) in salt-free solution. A maximum in reduced viscosity is obtained for a critical concentration attributed to a preferential intermolecular distance. This maximum seems to have the same origin as that observed by light or neutron scattering. Then, in excess of external salt, the viscosity of Na PSS is compared with that of polystyrene in organic solvent. The main difference between these two polymers is the large increase in the stiffness of the chain in the presence of ionic charge, causing large non-Newtonian behaviour of the polyelectrolyte when the polymer concentration increases even in 0.1 M NaCl.
