Abstract

Process for the preparation of lipophilic polyalkylenepolyamines by homogeneously catalyzed alcohol amination, where aliphatic amino alcohols are reacted with one another or aliphatic diamines or polyamines are reacted with aliphatic diols or polyols with the elimination of water in the presence of a homogeneous catalyst, at least one of the reactants comprising an alkyl or alkylene group having five or more carbon atoms, and after the reaction a phase separation into at least one apolar phase and at least one polar phase being present, the lipophilic polyalkylenepolyamines being present in enriched form in the apolar phase. 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 in 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.
