Aromatic polyimides have 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 polyamides were not dissolved in most organic solvents and were difficult to process due to intermolecular interactions. In order to improve solubility and processibility with maintaining thermal stability, amide group was combined with polyimide. In this study, it was investigated the effects of catalyst type and reaction time for polyamide-imide synthesis. |
