Abstract
Numerical computations of the electrostatic potential and the effective diffusion constant of counterions in a periodic polyelectrolyte solution are reported. Some results for the potentials for various polyion charge densities and polyion sizes are presented graphically. The calculated diffusion constants are compared with experimental data on the diffusion of labeled sodium ions in polyacrylic acid‐sodium hydroxide solutions as well as with the earlier approximate calculations.
