Structure & thermodynamics of polymer mixtures
The Random Phase Approximation (RPA) describes remarkably well the structure factor of homogeneous polymer mixtures, even highly interacting or with seriously asymmetric monomers. Phase separation via spinodal decomposition is reasonably well described by the Cahn-Hilliard theory, provided that the "early stage" is observable (ie, very close to the spinodal line, slow polymer dynamics).
