摘要：
Mixtures of a nematic liquid crystalline polyester with three model compounds of different molecular weights and mesogenic character were investigated. Experimental phase diagrams were constructed of binary mixtures of the polymer with each of the three low molecular weight materials, using DSC and optical microscopy measurements. Theoretical phase diagrams were calculated to qualitatively resemble the experimental ones by adjusting one free parameter, namely, the Flory chi parameter. The agreement between theory and experiment is good, and the trends with chi are physically reasonable.
