  A process is disclosed for preparing an aromatic polyimide separation membrane which comprises fluorinating an aromatic polyimide membrane with active fluorine. The aromatic polyimide separation membrane thus prepared has high selectivity and gas permeability and is therefore useful as a membrane for separation of gas mixture or liquid mixtures.

  本发明公开了一种制备芳香族聚酰亚胺分离膜的工艺，该工艺包括用活性氟氟化芳香族聚酰亚胺膜。由此制备的芳香族聚酰亚胺分离膜具有高选择性和气体渗透性，因此可用作气体混合物或液体混合物的分离膜。

  The invention relates to a separative membrane made of an aromatic polyimide, which is substantially constituted of a polyimide having the repeating units represented by general fomula (I) (wherein R represents a tetravalent aromatic group, and R¹ to R⁴ each represents an organic group containing 1 to 12 carbon atoms), and a process for preparing said membrane which comprises dissolving the aromatic polyimide described above in an organic liquid, forming a membrane from the solution, and heating the formed membrane at 200 °C or above.

  本发明涉及一种由芳香族聚酰亚胺制成的分离膜，它主要由具有通式(I)所代表的重复单元的聚酰亚胺构成（其中 R 代表四价芳香族基团，R¹至 R⁴ 各代表一个含有 1 至 12 个碳原子的有机基团），本发明还涉及一种制备上述膜的工艺，该工艺包括将上述芳香族聚酰亚胺溶解在有机液体中，从溶液中形成膜，并在 200 °C 或以上的温度下加热形成的膜。

  A resin film, in which at least one of polyimide layers is a non-thermoplastic polyimide layer having a linear thermal expansion coefficient of 1×10−6 to 30×10−6 (1/K), is shown. The non-thermoplastic polyimide layer is composed of a polyimide which is produced by reacting an anhydride component containing an aromatic tetracarboxylic anhydride with a diamine component, wherein the diamine component contains both a dimer acid-type diamine produced by replacing each of two terminal carboxyl groups in a dimer acid with a primary aminomethyl or amino group and an aromatic diamine, and the dimer acid-type diamine is contained in an amount of 1 to 15 mol % relative to the whole diamine component.

  图示为一种树脂薄膜，其中至少有一层聚酰亚胺层是线性热膨胀系数为 1×10-6 至 30×10-6 (1/K) 的非热塑性聚酰亚胺层。非热塑性聚酰亚胺层由聚酰亚胺组成，该聚酰亚胺是由含有芳香族四羧酸酐的酸酐组分与二胺组分反应生成的，其中二胺组分包含二聚酸中两个末端羧基分别被伯氨基甲基或氨基取代而生成的二聚酸型二胺和芳香族二胺，二聚酸型二胺的含量相对于整个二胺组分为 1 至 15 摩尔%。
