Title: Stretchable polymers and shaped articles produced by same

Abstract: A stretchable liquid crystal polymer having recurring units derived from p-hydroxybenzoic acid, 6-hydroxy-2-naphthoic acid, at least one aromatic diacid and at least one aromatic diol and/or hydroxyamine component, at least a portion of which is 4,4'-biphenol, and one or more aromatic monomers that provide the polymers with selected 1,3-(meta-) linkages. Stretchable polymers are especially suitable for multilayer laminates and bicomponent fibers.
