  A thermotropic mesogenic alkylene-aromatic poly(ether ester) was prepared by phase-transfer polycondensation of the azomethine derived from 5-amino-2-phenylbenzoxazole and 3,4-dihydroxybenzaldehyde with 1,6-bis(4-chlorocarbonylphenoxy)hexane in the presence of a phase-transfer catalyst, trimethylhexadecylammonium bromide. The intramolecular orientation order parameters and the angle formed by the pendant 5-imino-2-phenylbenzoxazole substituent relative to the backbone were estimated by methods of molecular hydrodynamics and optics.

  日期：1994.3

  The synthesis and liquid crystal behavior of new thermotropic polyurethanes derived from different mesogenic diols, alkylene di[4-(omega-hydroxyalkyloxy-4-oxybenzoyl)oxybenzoate]s, and 2,4-toluenediiso-cyanate are reported. Depending upon the chemical structure of the repeat unit, the polyurethanes formed either one or two mesophases extending over a fairly broad (>60 K) and accessible range of temperature (T-i < 430 K). A cybotactic nematic mesophase was identified in each polyurethane sample.
