Abstract
Un método de preparación de poliaminas por contacto de un polinitrilo con hidrógeno en presencia de un catalizador de hidrogenación en gránulos cilíndricos, caracterizado porque la reacción se lleva a cabo en presencia de un agente estabilizante no aromático que comprende una poliaminas con dos grupos amino como mínimo y un grupo hidroxi como mínimo, donde dichos grupos amino o dichos grupos amino e hidroxilo están separados por no más de 4 átomos de carbono, o de un derivado oxialquilado de dicha poliaminas o de dicha hidroxilamina.
