Aromatic polyimides hav been widely used in industry because of excellent properties in thermal stability, chemical resistance, and mechanical properties. But they have some disadvantages that most of aromatic polyimides were not dissolved in most organic solvents and were difficult to process due to intermolecular interactions. In order to improve solubiliby and processibility with maintaining thermal stability, amide group was combined with polyimide. in this study, it was investigated the effect of imide ratio on polyamide-imide resin |
