ABSTRACT:
Process for producing highly stretchable, amorphous anisotropic melt-forming polymers having recurring units derived from p-hydroxybenzoic acid, 6-hydroxy-2-naphthoic acid, at least one aromatic diacid and an aromatic diol and/or hydroxyamine component, at least a portion of which is 4,4'-biphenol, which comprises incorporating into such polymers recurring units derived from resorcinol and at least one additional monomer that provides the resulting polymer with selected meta linkages, wherein each of said recurring units is present in the polymer in specified amounts.
