Theoretical Estimation of Partial Miscibilities by the Extended Flory-Huggins Lattice Theory
Hae Young Jung, Mu Shik Jhon
Four types of the phase diagrams indicating the partial miscibilities in polymer-polymer or polymer-solvent systems have been explained in terms of the extended Flory-Huggins lattice theory. In this article, the term kTχ in the theory is expressed as a function of temperature. Using such aχ-parameter, the simplest forms of geometrical conditions are derived for each type of the four partial miscibilities in polymer systems. The calculated partial miscibilities are in good agreement with the experiment.
