ABSTRACT:
Liquid crystalline polymer having repeat units derived from 4,4′-biphenol, terephthalic acid, 2,6-naphthalenedicarboxylic acid, and 4-hydroxybenzoic acid in a limited compositional range have melting points of 400° C. or more, and are useful for molded articles and for films, particularly for uses where good high temperature resistance is needed.
