Flüssigkeitsähnliche Struktur in Suspensionen von Sulfonlatexkugeln

Abstract

Abstract By emulsion polymerization of styrene and vinylbenzene sulfonic acid monodisperse latex particles with sulfate and sulfonate surface groups were prepared. After careful cleaning, solid‐ and liquid‐like ordered suspensions of different particle concentration were obtained. Static and dynamic light scattering as well as electron micrographs were used to determine the particle size. Further, pH and conductivity experiments were carried out for the determination of the latex particle charge. For liquid‐like ordered suspensions of different concentrations the structure factor S(Q) and the radial distribution function g(r) are presented. These two quantities are discussed in terms of the rescaled mean spherical approximation (RMSA) of Hansen and Hayter.
