Abstract

We demonstrate here a dynamic phase transition between a periodic state without coarsening and a nonstationary state with coarsening, for a binary polymer mixture periodically driven above and below its instability point. For a nonstationary state we have found, in both symmetric and off-symmetric mixtures, the growth of a two-level structure characterized by two length scales. There is no self-similarity in this pattern evolution. A dynamic phase diagram of the dynamic stability of the phase has been obtained for the first time: Hydrodynamic interaction is found to have a strong effect on the dynamic stability limit through its dependence on the composition symmetry.
