Polyelectrolyte Complexes on a Dimeric Interface

Abstract
Thin films of the polyelectrolyte complexes between poly-2-vinylpyridine (poly-2-methyl-5-vinylpyridine) and sodium polystyrenesulphonate (polyacrylic acid) at benzene-water phase boundary have been synthesized. Polycomplex compositions and their stability to action of solvents, temperature and pH have been determined. The behaviour of polycomplexes in mixed organic solvents is compared to predictions of the Dondos-Patterson theory for viscosity of individual polymers in mixed solvents. It allows us to consider the polymer complexes formed on a dimeric interface as new individual nonpolar polymers.
