Process for producing highly stretchable, amorphous anisotropic melt-forming polymers consisting essentially of recurring units derived from p-hydroxybenzoic acid, 6-hydroxy-2-naphthoic acid, an aromatic diacid, at least a portion of which comprises 2,6-naphthalene dicarboxylic acid, 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, wherein each of said recurring units is present in the polymer in specified amounts.
