IMIDE GROUP-CONTAINING COMPOUND SOLUTION AND METHOD FOR PRODUCING POLYIMIDE FILM DERIVED FROM IMIDE GROUP-CONTAINING COMPOUND SOLUTION |
摘要 |
Provided is an imide group-containing compound solution which includes an imide group-containing compound obtained by partially hydrolyzing a polyimide molded article, a solvent, and a viscosity stabilizer and is excellent in long-term storage stability.;It is an imide group-containing compound solution including an imide group-containing compound obtained by partially hydrolyzing a polyimide molded article, a solvent, and a viscosity stabilizer. In the imide group-containing compound solution, an absorption peak derived from an imide group is observed at a wavenumber of 1,375 cm−1, an absorption peak derived from an amide group is observed at a wavenumber of 1,600 cm−1, and an absorption peak derived from a carboxyl group is observed at a wavenumber of 1,413 cm−1 in an infrared spectroscopy chart obtained by an infrared spectroscopic measurement of the imide group-containing compound and the viscosity stabilizer is an orthocarboxylic ester and a chelating agent or either one of the two. |
