Process for increasing the molar mass of polyalkylenepolyamines by homogeneously catalyzed alcohol amination, which comprises carrying out a reaction of the polyalkylenepolyamines in a reactor with elimination of water in the presence of a homogeneous catalyst and removing the water of reaction from the reaction system. Polyalkylenepolyamines obtainable by such processes, and polyalkylenepolyamines comprising hydroxyl groups, secondary amines or tertiary amines. Uses of such polyalkylenepolyamines as adhesion promoters for printing inks, adhesion promoters in composite films, cohesion promoters for adhesives, crosslinkers/curing agents for resins, primers for paints, wet-adhesion promoters for emulsion paints, complexing agents and flocculating agents, penetration assistants in wood preservation, corrosion inhibitors, immobilizing agents for proteins and enzymes. |
