Prediction of Phase Diagram Topologies

In this section, we shall describe the various topologies of possible phase diagrams using the proposed thermodynamic model for a crystal-amorphous blend. Most polyolefin blends exhibit either an LCST or a UCST or a combination of both. In order to model the combined LCST-UCST or hour-glass phase diagram, the 

Applying the conditions that = Xcut at the critical temperature of the UCST and LCST, one can treat these coefficients to be a function of only a single adjustable parameter A, that is.
