Small-angle neutron scattering (SANS) measurements were carried out on two series of ion-exchanged charged polystyrene latex (average particle diameters: 340 and 380A) dispersions in deuterated water [88%(v/v) D20] with particle volume fractions between 0-0075 and 0.074. Absolute scattering intensity profiles obtained were fitted to a model based on generalized one-component macroion theory to evaluate average particle diameter with the polydispersity and effective surface charge. The particle size parameters computed agreed well with electron microscopy data. However, effective surface charges obtained were only 6-7% of that determined by conductometric titration.
