ABSTRACT:
Melt-processable polyaramide and polyarylate polymers and copolymers are made employing a component containing the 5-t-butylisophthaloyl moiety and aromatic diamines or aromatic diols. The melt processability of these polymers can eliminate expensive processing in making shaped articles. The claimed materials are useful for making fiber, film, laminates, coatings, adhesives and molded objects.
