| titleOfInvention | Method for producing polyamic acid solution and polyamic acid solution |
| abstract | A diamine component comprising 20 to 80 mol% of paraphenylenediamine and 80 to 20 mol% of diaminodiphenyl ether and 10 to 60 mol% of 2,3,3 ', 4'-biphenyltetracarboxylic acid A process for producing a polyamic acid solution by reacting a tetracarboxylic acid component comprising 2-anhydride and 3,3 ', 4,4'-biphenyltetracarboxylic acid dianhydride in an amount of 90 to 40 mol% And an excess molar amount of the tetracarboxylic acid component relative to the diamine component in a solvent containing water in an amount exceeding 1/3 molar amount relative to the tetracarboxylic acid component to prepare a polyamic acid solution And then adding a diamine component, a diamine component and a tetracarboxylic acid component to the polyamic acid solution such that the diamine component and the tetracarboxylic acid component are substantially equimolar amounts, Relates to a process for producing a polyamic acid solution characterized in that the box. |
