Abstract | We apply dynamic scaling to both unentangled and entangled semidilute polyelectrolyte solutions. The unentangled semidilute regime can span three to four decades of polymer concentration in low-salt solutions. In this range we predict such phenomena as a concentration independent self-diffusion coefficient, relaxation time that is a decreasing function of concentration c, and explain the empirical Fuoss law for the viscosity η∼c1/2. In the low-salt entangled regime we predict the concentration independent relaxation time and the viscosity η∼c3/2 that are observed experimentally. |
