摘要：

From the measurement of the critical temperatures at the consolute point in binary solutions of different fractions of a side-chain liquid crystalline polymer in a liquid crystalline solvent we obtain the first evaluation of Flory's interaction parameter in the isotropic and nematic phases. We show that the modification of the solubility from the isotropic to the anisotropic phase results simply from a coupling with the nematic orientational order parameter. The calculation of the binodals from Flory's equation offers a remarkable agreement with the experimental curves of solubility. © 1990, American Chemical Society. All rights reserved.
