A direct measurement of the polyion conformation in aqueous solutions at different temperatures. Small angle neutron scattering of PSSNa using zero average and full contrast
The intrachain correlations in polystyrene sulfonate of sodium (PSSNa) have been measured as a function of the temperature, in semidilute solutions, using the zero average contrast technique. No temperature effect is observed. We also display and discuss data on interchain correlation, which are obtained from a scattering experiment at full contrast.
