Zusammenfassung:A liquid aliphatic polyamine material comprises an aliphatic polyamine and has a characteristic such that when the liquid is air-tightly contained in a container together with a gas and kept at 20 DEG C, the ammonia concentration in the gas in an equilibrium is at most 100 ppm. In a method of producing the aliphatic polyamine material, volatile odor components are removed from a liquid comprising an aliphatic polyamine, and the liquid is then sealed in an air-tight container, with substantially no oxygen contained therein. The odor of the liquid is thereby reduced to a very low level.
