Melt-fusible copolyimides based on pyromellitic anhydride and two defined classes of aromatic diamines, at least one diamine of each class being incorporated into the polyimide, each diamine class being present in an amount of 10-90 mole percent of the total diamine content (100 mole percent), melt below about 400°C and can be fabricated into articles, or can be applied to either fibrous or nonfibrous substrates to make prepregs, tapes, etc., which then are shaped into final articles, such as printed circuit boards or aircraft panels.
熔融型共聚多亚胺基于吡咯烷酮酸酐和两类确定的芳香族二胺,每类二胺中至少有一种掺入聚酰亚胺中,每类二胺的含量占二胺总含量(100 摩尔%)的 10-90 摩尔%,熔融温度低于约 400°C,可制成制品,也可应用于纤维或非纤维基材,制成预浸料、胶带等,然后将其成型为最终制品,如印刷电路板或飞机面板。
