Abstract: BIAXIALLY ORIENTED ORDERED POLYMER FILMS              ABSTRACT OF THE DISCLOSURE     This invention relates in general to the formation of multiaxially (e.g., biaxially)  oriented films from high molecular weight  lyotropic or thermotropic polymers  (homopolymers,  copolymers,  and the like), wherein due to the processing conditions employed, the films have a controlled molecular orientation.   The films of the present invention are preferably prepared from rod-like extended-chain, aromatic- heterocyclic polymers.   These polymers generally fall  into two classes;  first,  those that are modified in solution form, i.e., lyotropic liquid crystalline polymers; and second, those that are modified by temperature changes, i.e., thermotropic liquid crystalline polymers.  For a shorthand expression covering both types of polymers, the present disclosure will use the term "ordered polymers."
