    • Copolymers of the amide-imide variety are made from a mixture of two or more largely- or wholly-aromatic primary diamines and an aromatic polycarboxylic-acid-anhydride derivative. A process for fabricating molded articles from these copolymers is described which comprises heat treating the copolymers from about 300.degree. to about 700.degree. F. and then applying a pressure of about 200 p.s.i. to about 30,000 p.s.i. to said partially cured material which has been preheated to a temperature within the range of about 200.degree. to about 750.degree. F. and subsequentlyejecting the coalesced polyamide-imide in the form of a shaped article.
    • 酰胺 - 酰亚胺衍生物的共聚物由两种或多种主要或全部芳族伯二胺和芳族多元羧酸酐衍生物的混合物制成。 描述了由这些共聚物制造模塑制品的方法,该方法包括将共聚物热处理约300至约700°F,然后施加约200p.s.i的压力。 至约30,000 p.s.i 所述部分固化的材料已被预热至约200至约750°F的温度,随后将成形制品形式的聚结聚酰胺 - 酰亚胺喷射。
