A salt of a polymeric acid with an oxalkylated or amine-alkylated amine of the general formula ##STR14## wherein A=H, --OR.sub.2 or ##STR15## R.sub.1 is a lower alkyl, hydroxyalkyl, aminoalkyl, polyalkyleneimine or polyalkylene glycol ether radical;

• R.sub.2 is a lower alkyl radical, hydroxyalkyl, aminoalkyl, polyalkyleneimine or polyglycol ether radical;
• R.sub.3 is a lower alkyl radical, hydroxyalkyl, aminoalkyl, polyalkyleneimine or polyalkylene glycol ether radical;
• R.sub.4 is a lower alkyl radical, hydroxyalkyl, aminoalkyl;
• polyalkyleneimine or polyalkylene glycol ether radical;
• X is a bivalent alkylene radical having 1 to 6 carbon atoms;
• B is a lower alkyl radical, a hydroxyalkyl, aminoalkyl, polyalkylene glycol ether or polyalkyleneimine radical;
• n=an integer from 1 to 6 wherein when n=1 the group ##STR16## may be a bivalent 5- or 6-membered heterocyclic radical having 1 or more hetero atoms,
• at least one of the radicals R.sub.1, R.sub.2, R.sub.3, R.sub.4, and B being a polyalkylene imine or polyalkylene glycol ether radical.
