| titleOfInvention | Method for producing polyimide |
| abstract | (57) [Problem] To provide a production method for efficiently obtaining a high molecular weight polyimide. SOLUTION: An aromatic tetracarboxylic anhydride having 10 to 29 carbon atoms and an aliphatic and / or alicyclic diamine having 2 to 20 carbon atoms are obtained by combining benzyl alcohol with 6 carbon atoms. In a mixed solvent consisting of from 1 to 12 aromatic hydrocarbons. Furthermore, it is preferable to subsequently evaporate the solvent under heating and / or reduced pressure, and to further perform a melt heat treatment under reduced pressure. |
