Abstract

For a binary mixture of polydisperse polymers with strong interactions, the free energy, the equation of state, the chemical potentials and the spinodal are formulated on the basis of the lattice fluid model. Further, the spinodal curves for the system with strong interactions are simulated by using mixtures of special‐distribution polymers, i.e., Schulz distribution and uniform distribution. From comparison with the experimental results, it can be seen that the shift of the spinodal curves with the polydispersity and the strong‐interaction energy parameter is qualitatively identical with the conclusions of Nishi and Kwei, and Goh, Paul and Barlow.
