Phase-Separating Binary Polymer Mixtures: The Degeneracy of the Virial Coefficients and Their Extraction from Phase Diagrams (vol 6, pg 7862, 2021)

Summary: The Edmond-Ogston model is based on a truncated virial expansion of the Helmholtz free energy in binary polymer mixtures. The model's key parameters are the second virial coefficients. Analytical solutions are presented for the critical point and spinodal, with the calculation of the binodal simplified by splitting the problem into parts that may be solved analytically or numerically.
