Abstract: 
An analysis of the characteristic times of the polystyrene segmental motion estimated on the basis of the elastic and frictional viscosity components of the polystyrenes solutions has been done. The characteristic times of the translational motion and also the diffusion coefficients of polystyrene in diluted and concentrated solutions were calculated.
