摘要：

Dimethylformamide solutions of lightly sulfonated polystyrene (SPS) ionomers have been studied. These SPS polymers possess a narrow molecular weight distribution and are in the form of sodium salts. A combination of reduced viscosity and small-angle neutron scattering (SANS) measurements reveal polyelectrolyte effects in these solutions. Mixed-labeling experiments were performed to provide a molecular basis for understanding these effects.
