ABSTRACT:
A process for the manufacture of polyalkylenepolyamines by reacting a primary or secondary amine with a compound of the formula ##STR1## where X is --Cl, --Br, or --OSO.sub.3 H and R.sup.1 and R.sup.2 are H or saturated alkyl of 1 to 4 carbon atoms, and with at least the stoichiometric amount, based on the compound of the formula I, of an aqueous solution, of from 15 to 45 percent strength, of an alkali metal hydroxide or alkaline earth metal hydroxide, at from 60.degree. to 200.degree. C., cooling the reaction mixture to a temperature at which 2 aqueous phases form, and separating off the upper phase, containing polyalkylenepolyamnines. The rate of reaction can be increased by adding catalytic amounts of compounds which initiate the polymerization of alkyleneimines.
