| titleOfInvention | Method for producing polyisoimide solution |
| abstract | PROBLEM TO BE SOLVED: To provide a simple method for producing a polyisoimide solution comprising a polyisoimide and a solvent capable of obtaining a polyisoimide molded article having excellent heat resistance. SOLUTION: The structural unit represented by the following formula (1) is represented by 20 Mol% or more, the remainder being a polyamic acid solution comprising a polyamic acid comprising a structural unit represented by the following formula (2) and a solvent, adding a haloiminium salt and a basic substance to isoimidize the polyamic acid. A method for producing a polyisoimide solution, comprising: (In the formula, the group indicated by the arrow is as shown in the drawing or at the exchange position, and indicates isomerism.) (In the formula, the group indicated by the arrow is as shown in the drawing or at the exchange position, and indicates isomerism.) |
