Conventionally, polyimide resin is produced by mixing tetracarboxylic dianhydride and aromatic diamine in an organic polar solvent at 60°C.
In the following method, polyamic acid was produced by an addition reaction, and after molding, it was imidized using a dehydrating agent or heating (Japanese Patent Publication No. 10999/1983,
-97 Publication, Special Publication No. 37-10945, etc.). Furthermore, as a method for producing polyimide resin soluble in organic solvents, for example, Japanese Patent Publication No. 47-26878 describes at least
An aromatic diamine having an alkyl group at a position ortho to 60 mol% of an amino group and benzophenone tetracarboxylic dianhydride in cresol,
A method is described in which the reaction is carried out at a temperature of 160°C or lower. In addition, 1, 2,
A method for producing a polyimide resin using 3,4-butane tetracarboxylic acids as a tetracarboxylic acid component is described.
