ABSTRACT:
Improved polyphthalamide compositions which possess desirable heat resistance properties comprise a crystalline polyphthalamide component and a particulate thermotropic liquid crystalline polymer component in an amount sufficient to nucleate a melt of the polyphthalamide. Molded articles prepared from these compositions exhibit excellent mechanical and thermal properties, including expecially high crystalline uniformity throughout even when molded using molds heated below Tg of the polyphthalamide component, often facilitating molding using steam or hot water-heated molds.
