Chiral liquid-crystalline polymers

XII. New chiral polyesters by chemical modification of a nonmesophasic polymer

  • 34 Accesses

  • 9 Citations

Summary

The preparation is described of a new class of chiral liquid-crystalline polyesters by means of an acidic hydrolysis of the polyester based on 4,4′-(terephthaloyldioxy)dibenzoic acid and (+)-1, 2:5,6-di-O-isopropylidene-D-mannitol. Whilst the parent polymer is not mesogenic, the deprotected hydroxyl-containing polyesters give rise to anisotropic melts extending over a broad range of temperatures with a clearing point above 300°C.
