ABSTRACT:
The invention relates to aromatic polyesters containing units with two carbonyl groups and having liquid crystalline properties. The aromatic polyesters are characterized in that the polyesters contain heterocyclic units with two carbonyl groups. Preferably these units are derived from furandicarboxylic acid. The aromatic polyesters show a considerable reduction in melting temperature, rendering the polyester more processable.
