Popis:	The dynamical behavior of charged poly-acrylic acid solutions is investigated in the presence and absence of electrolyte using dynamic light scattering measurements. An interesting non-ergodic to ergodic transition is observed for polyelectrolyte solution with addition of excess salt. Our study shows two modes of diffusive processes that are greatly influenced by inter-molecular interactions occurring inside the charged polymer systems, which in turn affect the correlation length and thereby showing changes in structural behavior of the polyelectrolyte solutions.
