ABSTRACT:
A liquid aliphatic polyamine material, sealed in a container, has an ammonia concentration of at most about 100 ppm, and can be made by removing volatile odor forming components from a liquid comprised of aliphatic polyamine, and enclosing it in an air-tight container, with substantially no oxygen present, whereby the odor of the liquid aliphatic polyamine is reduced to a very low level even after extended storage.
