dc.description.abstractThe methods of dialysis equilibrium and static light scattering were used to study the properties of dilute solutions of sodium poly(styrenesulfonate) (M(w) = 3.5 x 10(5) gmol-1) at various ionic strengths, I. The dialysis equilibrium technique yielded the degrees of counterion condensation which are in good agreement with the theoretical predictions of Manning. Radii of gyration and second virial coefficients were determined by means of static light scattering. The experimental values of A2 Were compared to theoretical ones calculated for sphere and worm-like structurated polyions. For both models the agreement is qualitatively satisfactory but quantitatively worse. Best results are obtained if the theoretical expression for the worm-like polyion is corrected by taking into account chain flexibility. The ionic strength dependence of the radius of gyration, [S]z, was interpreted in terms of an increase of the electrostatic part of the persistence length, l(el), as the ionic strength is lowered. Eventually, [S]z, and l(el) reach limiting values both at very low and as well at very high ionic strengths, I.
