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 phenyl‐hydroquinone. Containing 5 or 10 mol‐% of isosorbide a “Grand‐Jean” texture is detected above 300°C and 350°C, respectively.
