It is seen that in 0.1 PAA/0.9 PHAB and in 0.7 PAA/0.3 PHAB mixtures that the densities in the biphasic regions follow a linear temperature dependence. This behavior is interpretated as being evidence that the relative fraction of coexisting isotropic phase decreases linear with decreasing temperature. © 1988.Mahidol UniversityPhysics and AstronomyOn the nature of the biphasic region in binary nematic liquid crystal mixturesArticleSCOPUS10.1016/0375-9601(88)90212-5
