thermotrope aromatic polyester with high waermeformbestaendigkeit and excellent mechanical properties, processes for their manufacture and their use in the manufacture of formkoerpern, filaments, fibres and films.

摘要

Thermotropic, fully-aromatic polyesters having a high content of 3,4'-benzophenonedicarboxylic acid radicals exhibit a combination, hitherto unknown, of good processability, high deflection temperature under load and very high strength and stiffness.
