ABSTRACT:
Liquid crystalline polyesters made from hydroquinone, terephthalic acid, 2,6-naphthalene dicarboxylic acid and 4-hydroxybenzoic acid, and having a selected composition range, have melting points of about 350.degree. C. or less, good physical properties, and are readily manufactured. The polymers are useful as molding resins.
