Zusammenfassung:The influence of the polarisation of the solvent on the mean dimensions of model polyelectrolytes is incorporated by solving numerically the Poisson equation for each conformation of the chain embedded in a continuous dielectric media. The mean squared end to end distance reveals the screening effect introduced by the charges induced within the dielectric. The highest departure from continuous dielectric models occurs at intermediate values of the Coulomb coupling strength.
