Abstract Of The Disclosure Improved polyphthalamide compositions, particularly for injection molding applications, comprise a polyphthalamide component with at least two recurring units selected from terephthalamide, isophthalamide and adipamide units and having high heat deflection temperature when filled with glass fibers; reinforcing fibers; and effective amounts of particulate talc. Molded articles prepared from such compositions exhibit excellent mechanical and thermal properties, including high heat deflection temperature, even when molded using molds heated below Tg of the polyphthalamide component, often facilitating molding using steam or hot water-heated molds.
