摘要:
Aromatic polyesters exhibiting melt processability are disclosed. The polyesters comprise repeating units of the formula ##STR1## wherein X is hydrogen, halogen, alkyl or nitro. The polyesters exhibit low-melting properties, melt processability and melt anisotropy. The aromatic polyesters can be melt processed to films and fibers.
