Polyamines having lipophilic residues, e.g. those described below, are reacted with epichlorhydrin. (1) 1 mol. of the methyl ester of hardened cottonseed oil fatty acids and 1 mol. of dipropylenetriamine were reacted together, and 400 parts by weight of the product melted in a stirred vessel under reflux. A mixture of 120 parts of epichlorhydrin and 100 parts of denatured ethanol was added and stirred at 80-90 DEG C. and then diluted with water. (2) 130 parts of saturated alcohol obtained by the hydrogenation of tallow fatty acids were melted in a stirred vessel under reflux, and 1 part of tin tetrachloride and 46.5 parts of epichlorhydrin added at 70 DEG C. The mixture was stirred at this temperature for 30 minutes, and then 33 parts of dipropylenetriamine and 44 parts of 50% caustic soda were added, and the mixture stirred for 45 minutes while heating to 120 DEG C. The product was washed with water, and, after the addition of 100 parts denatured ethanol, reacted at 80 DEG C. with epichlorhydrin and then diluted with water. (3) 130.5 parts of commercial hexadecyl chloride were stirred with 66 parts dipropyl triamine, 51 parts of 50% soda lye, and 60 parts of 96% denatured alcohol, and boiled under reflux. The sodium chloride formed was filtered off, and the filtrate reacted at 80 DEG C. with 93 parts of epichlorhydrin and then diluted with water. (4) 300 parts of N-hexadecylpropylenediamine were treated with 100 parts of 96% denatured ethanol in a stirred vessel. 140 parts of epichlorhydrin were added at 70 DEG C. with stirring, and the mixture boiled under reflux, and then diluted with water. (5) 270 parts of N-dodecyl-p-cyclohexylenediamine were stirred with 80 parts of 96% ethanol, and 140 parts of epichlorhydrin added at 75 DEG C. The reaction mixture was boiled under reflux, and then diluted with water. The products may be used for waterproofing (see Group VIII).
