Light scattering and ultra-violet absorption studies on dilute aqueous solutions of poly-4-vinylpyridinium chloride

Abstract The discontinuous concentration of viscosity, streaming birefringence and conductance of dilute aqueous solutions of poly-4-vinylpyridinium chloride is attributed, on the basis of light scattering and spectra measurements, to the extensive hydrolysis of the poly-ions in dilute solution. The decrease in the charge on the poly-ion consequent on the hydrolysis produces changes in the shape and size which may explain the observed hydrodynamic properties.
