Abstract: The invention relates to graft polymers, the graft foundation thereof being selected from the group of polymers having vinyl amine units, polyamines, polyamidoamines, and polymers of ethylenic unsaturated acids, and which exclusively contain oligoalkylene imine side chains as side chains, methods for the production of graft polymers having oligoalkylene imine side chains, wherein at least one oligoalkylene imine, which contains a terminal aziridine group, is grafted onto one of the cited graft foundations, and use of the graft polymers thus obtained as processing chemicals in the production of paper, as antimicrobial coating agents, as builders in detergents, and for treating metal surfaces.
