ABSTRACT:
A melt processable wholly aromatic liquid crystalline polymer capable of forming an anisotropic melt phase at a temperature below approximately 400.degree. C. having enhanced adhesion properties containing from approximately 0.05 to approximately 2.0 mole percent of a recurring sulfonated, ionic moiety in the backbone of the polymer. The polymer is useful for the production of laminate structures.
