5 kg, an equimolar salt of isophthalic acid and hexamethylenediamine (0.45 kg) and pure water (2.5 kg) were charged into a 5-liter autoclave and sufficiently purged with nitrogen while stirring. The temperature was raised from room temperature to 220 ° C. in about 1 hour while stirring was continued. Thereafter, the temperature was raised to 260 ° C. over about 2 hours while removing water from the reaction system so that the internal pressure of the autoclave became 18 kg / cm 2 -G. Thereafter, the heating was stopped, the autoclave was closed, and cooled to room temperature over about 8 hours to obtain about 2 kg of a polymer. The obtained polymer was pulverized and subjected to solid-phase polymerization at 200 ° C. for 10 hours under a nitrogen stream using a 10-liter evaporator to further increase the molecular weight. The formic acid solution viscosity becomes 1 due to solid state polymerization.
