Abstract

Intrinsic viscosity of aqueous solutions of nonionic surfactants TritonX-114 at T = 298K, 303K, 308K and 313K in presence and in absence of polyelectrolyte polyvinyl sulphonic acid are determined. The intrinsic viscosities [η] presumably so named because it is an intrinsic function of the dissolved or dispersed macromolecules. The ηsp is directly proportional to the concentration (c) of solution. Intrinsic viscosity values have been used to discuss structural alteration and molecular interactions. Intrinsic viscosity of polyelectrolyte-surfactant solution was determined in presence of various amounts of surfactants TritonX-114, it was observed that values increase as the temperature of the system increases, indicating increase in solvent power and solubility of PVSA.
