  A novel polyimide which retains the characteristics of polyimides, that is, excellent heat resistance, electrical insulation and chemical resistance, of which dielectric constant is lower than those of the known polyimides, as well as a composition containing the same and a process for producing the same, is disclosed. The polyimide of the present invention is a cross-linked polyimide having a dielectric constant of not more than 2,7, which was produced by polycondensing (a) tetramine(s), (a) tetracarboxylic dianhydride(s) and (an) aromatic diamine(s) in the presence of a catalyst.

  本发明公开了一种新型聚酰亚胺，它保留了聚酰亚胺的特性，即优异的耐热性、电绝缘性和耐化学性，其介电常数低于已知聚酰亚胺的介电常数，还公开了含有这种聚酰亚胺的组合物和生产这种聚酰亚胺的工艺。本发明的聚酰亚胺是一种介电常数不超过 2.7 的交联聚酰亚胺，它是通过在催化剂存在下将(a)四胺、(a)四羧酸二酐和(an)芳香族二胺缩聚而成。
