  Coolyimides and copolyamide-acids having improved solubility and processing characteristics are provided having incorporated into the polymeric chain as a novel aromatic diamine compound, 2-(3-aminophenyl)-2-­(4-aminophenyl) hexafluoropropane (3,4′-6F Diamine). The copolyamide-acids and copolyimides are prepared by reacting the 3,4′-6F Diamine with a mixture of two or more aromatic tetracarboxylic acids or anhydrides thereof. It has been found that the copolyimides of this invention have improved solubility characteristics, low dielectric constants and improved thermal flow properties as a consequence of the meta/para positioning of the amino groups on the diamine, which renders these copolymers more readily melt spinnable for the production of fibers. The copolymers may also be compression molded and fabricated into composites at moderate temperatures and pressures. Solutions of the copolyimides may be cast into films.

  在聚合物链中加入新型芳香族二胺化合物 2-(3-氨基苯基)-2-(4-氨基苯基)六氟丙烷(3,4′-6F 二胺)，可提供具有更好溶解性和加工特性的共聚多酰胺-酰亚胺和共聚多酰胺-酰亚胺。共聚多酰胺酸和共聚多亚胺是通过 3，4′-6F 二胺与两种或两种以上芳香族四羧酸或其酸酐的混合物反应制备的。研究发现，本发明的共聚亚胺具有更好的溶解特性、更低的介电常数和更好的热流特性，这是因为二胺上的氨基具有偏/对位定位，从而使这些共聚物更容易熔融纺丝，用于生产纤维。这些共聚物还可以在中等温度和压力下压缩成型并制成复合材料。共聚亚胺的溶液可浇铸成薄膜。
