“…The usual polystyrene latices (PSt) were prepared by the method of Furusawa et al [7], and the other two, (PStm, PStn), were synthesized by incorporating small amounts of ionic comonomer, methacrylic acid (MA) and sodium p-vinylphenylsulfonate (NaSS) into a polystyrene chain, respectively, as in Juang et al [8]. To increase the particle 9 .…”

“…These latex samples were sufficiently dialyzed with distilled water and were then brought into contact with an ion exchange resine (Amberlite MB-3) to remove ionic impurities. These samples were all composed of highly monodispersed spherical particles with Dw/Dn < 1.02, and the surface charge densities of the latex particles were measured by potentiometric and conductometric titration, as in Vanderhoff et al [9]. The titration curves are shown in Fig.…”

~'-potentials of a silica suspension and three types of polystyrene latex suspensions with different surface charge groups were measured, as a function of the particle concentration (~) in the suspension over a wide range, using the colloid vibration potential (CVP) technique. The concentration dependence of the F-potential in silica suspension is explained well by Levine et al.'s [1] cell model theory, verifying the applicability of the cell model to the CVP in silica suspension. However, the ~'-potentia! of latex suspensions ordinarily decreases as the particle concentration increases, even after being corrected by the term of (1-r This tendency is especially noticeable in the systems that have particles with high surface charge densities. Furthermore, the conductivity measurements of these suspensions reveal that the conductivity of these systems, especially in their highly charged state, increases as the particle concentration is increased; opposite in tendency to silica suspensions. These new findings can be explained as follows: on the highly charged surface of a latex particle, a polyelectrolyte-like ("hairy") layer is present, which overlaps at some point. This permits interparticle surface conduction and results in the abnormal behavior of CVP in these systems.
