  A process by which a polyamide, polyimide, or polyamide-imide capable of being easily purified after reaction, especially an aromatic polyamide (aramid), aromatic polyimide, or aromatic polyamide-imide, which is difficult to synthesize by direct polycondensation, is produced in high yield from a polycarboxylic acid and a polyamine by direct polycondensation with heating while inhibiting side reactions, e.g., one accompanied by a color change into black. An aromatic dicarboxylic acid, aromatic tetracarboxylic acid, or aromatic tricarboxylic acid is condensation-polymerized with an aromatic diamine using an arylboric acid, e.g., 3,4,5-trifluorophenylboric acid, as a polycondensation catalyst in the presence of either a mixed solvent comprising pentamethylbenzene and N-methylpyrrolidinone or a mixed solvent comprising m-terphenyl and N-butylpyrrolidinone to obtain a polyamide, polyimide, or polyamide-imide in high yield.
