Abstract

Concentration dependence of radius of gyration (R_g) of sodium poly(styrenesulfonate)s (NaPSS) in aqueous solutions without added salt was studied by small-angle neutron scattering measurements over a wide range of concentration. The R_g values are always higher than those of corresponding nonionic polymer, polystyrene, and the concentration (C) dependence of R_g of NaPSS in the semidilute region (C<0.3×10³kg/m³) can be well expressed by the scaling relation (R_g∝C^-1/4). The crossover concentration from the semidilute to concentrated regions was also consistent with our previous studies of viscoelastic properties of polyelectrolyte solutions without added salts.
