Abstract

Fundamental parameters in the Flory-Huggins theory of binary mixture, including the heat of mixing associated with pairwise interactions ( Δw12) and the coordination number, z, are calculated through molecular simulations. The pair energies (w11, w22, w12) are obtained by averaging a large number of configurations generated by a Monte Carlo approach which includes the constraints associated with excluded volume. The temperature dependence of the interaction parameter X is obtained from this study.
