摘要：

A series of chiral copoly(ester-imide)s was prepared by polycondensation of N-(4-carboxy-phenyl)trimellitimide with mixtures of isosorbide and phenylhydroquinone. All copolyesters are non-crystalline. They form a cholesteric melt, when containing more than 50 mol-% of phenylhydroquinone. Containing 5 or 10 mol-% of isosorbide a ''Grand-Jean'' texture is detected above 300 degrees C and 350 degrees C, respectively.
