Abstract
The authors conducted dynamic light scattering measurements for sulfonated polystyrene ionomers, which were previously used for viscosity and low-angle light scattering experiments. The purpose of the work is to obtain additional information on ionomer/polar solvent systems, to compare these data with those obtained for salt-free polyelectrolyte/water systems, and to elucidate the essential factors causing polyelectrolyte behavior. It is shown that at least two different concentration regions were observed for ionomers of higher molecular weight (4×105) in the experimental range studied (10-4-10-2 g/cm3), while only one region was observed for the samples of lower molecular weight (5×104) in the same concentration range studied. This seems to reflect the difference in the critical concentrations for the ionomer samples with different molecular weight.
