| titleOfInvention | Organic-solvent-soluble polyimide comprising PMDA, DADE, BPDA, and BCD |
| abstract | Disclosed is an organic-solvent-soluble, heat-resistant polyimide that comprises (a) a pyromellitic dianhydride (PMDA), (b) a biphenyl tetracarboxylic dianhydride (BPDA), (c) a bicyclooctene tetracarboxylic dianhydride (BCD), and (d) a diaminodiphenyl ether (DADE) as components. The organic-solvent-soluble, heat-resistant polyimide has a thermal decomposition initiation temperature in the range of 530 DEG C to 570 DEG C and is synthesized by means of a three-step hydrogenation reaction: in the first step, a low molecular weight imide compound is generated by the reaction of an acid dianhydride and an aromatic diamine; in the second step, a low molecular weight imide compound is generated by further reacting an acid dianhydride and an aromatic diamine with the low molecular weight imide compound generated in the first step; and in the third step, a polycondensation reaction is performed. |
