    Abstract

    The stationary dynamics approach to analytical approximations for polymer coexistence curves was studied. It was found that the approach became an approximation when the fluxes, written in terms of diffusion coefficients, were calculated analytically instead of numerically. It was demonstrated that the stationary dynamics approach also yielded approximations for coexisting phases in symmetrical multicomponent systems, though the accuracy decreased as the number of coexisting phases increased. The fast and slow mode flux expressions for a specific nonstationary situation were also analyzed.
