1 Introduction
During the last decades there has both in academia and in industry been lots of attention to the phase behaviour of polymer blends. Industrial applica tions tend to use still more complex polymeric systems, where the miscibility parameters play an essential role. 1 There is therefore a broad economic interest on the exploration of basic thermodynamic equilibrium properties as well as gain of better understanding on the non-equilibrium behaviour.
