摘要：

Continuous thermodynamics is a suitable tool for describing the thermodynamic properties of solutions of polydisperse polymers. To represent Liquid-liquid equilibria of polydisperse polymer/solvent systems, a continuous distribution function to represent the composition of polydisperse polymers has to be considered. In this study, we calculate the molar mass distributions of both principal phases and conjugate phases, using the extended Flory-Huggins model. The results for various polydisperse polymer systems are compared with experimental data. (C) 1999 EIsevier Science B.V. All rights reserved.
