Phase Diagram Calculation for Binary Crystalline Polymer Blends

Phase Diagram Calculation for Binary Crystalline Polymer Blends 

The first term in braces represents the Landau-type free energy of crystal solidification of each component in which the individual free energy of the constituents is weighted by the respective volume fractions to ensure that these potentials vanish at the extreme limits of zero crystallinity or if a component is non-crystallizable. The second term represents the entropic part of the free energy of mixing of the amorphous constituents. In the third term, Xaa corresponds to the amorphous-amorphous interaction parameter of Flory-Huggins that characterizes the stability of the liquid phase. 

The anisotropic interactions such as crystal solid-amorphous liquid or amorphous liquid-crystal solid interactions may be defined as Xca i Xac- respectively. The coupling term representing the crystal-amorphous interaction with volume fraction (or concentration) may be regarded as
