| titleOfInvention | Process for producing polycondensate from polycarboxylic acid and polyamine |
| abstract | This invention provides processes of the preparation of polyamides, polyimides, and polyamideimides, which are easy to purify after reactions, from polycarboxylic acids and polyamines in high yield without side reactions such as a change of color to black by direct polycondensation reaction with heat, especially processes of preparing aromatic polyamides (aramids), aromatic polyimides, and aromatic polyamideimides, which are difficult to synthesize in direct polycondensation reaction. Polyamides, polymides, and polyamideimides are prepared in high yield by the polycondensation of aromatic dicarboxylic acids, aromatic tetracarboxylic acids or aromatic tricarboxylic acids and aromatic diamines, using arylboric acids such as 3,4,5-trifluorophenylboric acids as polycondensation catalysts, in a mixed solvent of pentamethylbenzene and N-methylpyrrolidinone or a mixed solvent of m-terphenyl and N-butylpyrrolidinone. |
