Interaction between sodium polystyrenesulfonate and Triton X-100 in aqueous solution

The interaction between sodium polystyrenesulfonate (PSS) and Triton X-100 (alpha-(4-octylpenyl)-poly(oxyethylene), TX-100) has been investigated by viscosity and conductivity measurements. The results show that the reduced viscosity of PSS increases with increasing PSS concentration at low constant TX-100 concentrations (0.006-0.029 g/ml). On the other hand, at higher constant TX-100 concentrations, 0.048 and 0.062 g/ml, the reduced viscosity decreases with increasing PSS concentration. The behaviour of conductivity of PSS in pure water is quite different from that in the presence of TX-100.
