Abstract

Electrophoretic mobilities are studied in polyelectrolyte‐plus‐salt solutions, using linear irreversible thermodynamics and the concepts of relaxation and electrophoretic effects discussed in paper I. If ionic interactions are treated within the Debye‐HΓΌckel approximation, co‐ions contribute significantly to the relaxation field experienced by polyions. Moreover, through self‐diffusion and electrophoretic measurements, the effective valance of the polyion becomes an experimentally accessible parameter. It should provide another method to check the concept of ion condensation.

Relaxation dynamics of salt-free, aqueous solutions of sodium poly(styrene sulfonate) (NaPSS) were investigated by mechanical rheometry and flow birefringence measurements. Two semidilute concentration regimes were studied in detail for a range of polymer molecular weights. At solution concentration

It is suggested, when working with drug-urea-water systems, that more than passing consideration be given to the effect or effects produced by addition of a fourth component, as, for example, when an acid is used to adjust pH. Data are cited which indicate that these effects are measurable and often
