The present invention provides a method for producing a polyimide varnish, the method comprising: a polycondensation step in which one or more tetracarboxylic acid dianhydrides and one or more diamine compounds are subjected to a polycondensation reaction, thereby obtaining a reaction product (x); a step in which an organic solvent is subjected to inert gas bubbling, thereby obtaining a solvent (y) for dilution; and a dilution step in which the reaction product (x) and the solvent (y) for dilution are mixed with each other, thereby obtaining a polyimide solution that has a dissolved oxygen concentration of 0.23 mg/L or less. Consequently, the present invention enables the achievement of a varnish which contains a solvent-soluble polyimide, while being free from coloring and exhibiting excellent colorlessness.
The present invention provides a method for producing a polyimide, the method comprising: a step 1 in which a diamine solution is obtained by dissolving a diamine in an organic solvent, and a tetracarboxylic acid dianhydride is added to and mixed with the diamine solution so as to obtain a homogeneous solution; and a step 2 in which the tetracarboxylic acid dianhydride and the diamine are polycondensed with each other. With respect to this method for producing a polyimide, in the step 1, it is regulated such that the diamine solution does not exceed 100°C from the time when the addition of the tetracarboxylic acid dianhydride is started to the time when the solution becomes homogeneous. Consequently, the present invention enables the achievement of: a varnish which has a viscosity sufficient for coating; and a polyimide which has excellent colorlessness.
The method for producing a polyimide varnish polycondenses one or more tetracarboxylic dianhydrides and one or more diamines in an organic solvent at a reaction temperature of 160-220°C to obtain a reaction solution and lowers the temperature of the reaction solution from the reaction temperature to 120°C at a rate of 4°C/min or more by introducing a diluting solvent to stop the reaction. A method for producing a polyimide varnish that contains a solvent-soluble polyimide, has no coloration, and can obtain a varnish having excellent colorlessness can be provided according to the present invention.
