실험 절차

50 wt % aqueous solution of salt (AH salt) of adipic acid with hexamethylenediamine, and ∈-caprolactam (CL) were mixed so that AH salt was 20 parts by weight and CL was 80 parts by weight, and the mixture was charged in an autoclave of 30 liters. After it was raised to 270° C. at an internal pressure of 10 kg/cm2, the internal temperature was maintained at 245° C., while stirring, the pressure was slowly reduced to 0.5 kg/cm2 and stirring was stopped. After being returned to normal pressure by nitrogen, a strand was drawn out, pelletized, and unreacted substances were extracted out using boiling water, and dried. The thus obtained copolyamide 6/66 resin had a relative viscosity of 4.20 and melting point of 193° C.
