Abstract
Miscibility of dimesogenic, nematic, compounds with main chain nematic or cholesteric polymers having flexible spacers was examined by differential scanning calorimetry on a polarizing microscope. The four pairs studied in the present investigation revealed complete miscibility in mesophases. In solid state, however, they showed more complicated behavior. When the structures of a polymer and a dimesogenic compound were similar, eutectic formation was observed. No eutectic formation was detected when the structures of the pair were not similar. The Schr der-van Laar equation melting temperatures only for two systems among the four pairs of mixtures studied.
