Thermotropic aromatic polymers with high elongation at break, processes for their preparation and their use for the production of moulded articles, filaments, fibres and films

摘要

Thermotropic, fully aromatic polyesters based on p-hydroxybenzoic acid, aromatic dicarboxylic acid and diphenol in which the dicarboxylic acid groups consist at least in part of 3,3'-diphenyldicarboxylic acid groups have excellent mechanical properties, in particular excellent elongation at break.
