THERMOTROPIC AROMATIC POLYESTERS HAVING EXCELLENT MECHANICAL PROPERTIES AND A GOOD PROCESSABILITY, PROCESS FOR PREPARING THEM AND THEIR USE IN THE PRODUCTION OF MOULDED ARTICLES, FILAMENTS, FIBRES AND FILMS

摘要

Fully aromatic polyesters which contain 3-phenyl-4,4'-dihydroxybenzophenone radicals and/or 3-phenyl-3',4-dihydroxybenzophenone radicals as condensed units possess high mechanical properties but can still be processed without difficulties by a thermolastic method.
