Abstract
A class of aromatic polyesters exhibiting melt processability is disclosed. A portion of repeating 2,2'-substituted-biphenylene radicals in an aromatic polyester is replaced by certain other aromatic radicals to provide an aromatic polyester which exhibits low-melting properties, melt processability and melt anisotropy. The aromatic polyesters can be melt processed to films and fibers.
