inelastic light scattering experiments demonstrate the existence of a conformational change upon ionization of a weak acid poiyelectrolyte in aqueous salt solutions. The swelling of the polymeric coil occurs at a neutmlization degree increasing with mofecnlar weight.

β¦ Synopsis
The neutron scattering intensity from polyelectrolyte solutions is calculated using an asymmetric primitive model electrolyte for the computation of the partial structure factors and a Debye function for the polyion form factor. The variation of the intensity with wavevector and concentration agrees with experimental results.

The small-angle scattering of a polyelectrolyte solution in the dilute and semi-dilute regimes is calculated for systems in the absence of added salt. The calculation is based on a one-component plasma macrofluid reference fluid for the interchain interaction and has the qualitative form and concent
