Abstract
In an earlier paper, the authors reported a mean field model for reproducing the double reentrant phase sequence of a pure compound with strong polar end groups. The present work is an extension of the earlier model to the case of a binary mixture consisting of a polar and a nonpolar component. The calculated phase diagram shows that the double reentrant polymorphism ceases to exist beyond a certain fraction of the nonpolar component. This aspect and other features of the phase diagram are in good qualitative agreement with experimental observations in some cases.
