Beschreibung
Zusammenfassung:	A water-soluble organic polybase which is useful for the cationization of asbestos-free, cellulose fiber filter media is prepared by reacting a mixture of a compound of the formula R2-CO-R1-COOH and a polyalkyleneimine with a difunctional alkylating agent, wherein R1 is a single bond or alkylene having 1 to 10 carbon atoms and R2 is inter alia a moiety of the formula H2N-(CH2)u-NH-(CH2)u-NH)w wherein u is the number 2, 3, 4 or 5 and w is the number 0, 1, 2 or 3.
