Claims
- 1. A cationic water soluble resin consisting essentially of the reaction product of (1) a water soluble or water dispersible polyaminopolyamide--epihalohydrin base resin having epoxide moieties and (2) a nitrogen compound in an amount at least stoichiometrically equivalent to the epoxide moieties of the base resin, said base resin consisting essentially of the reaction product of a dicarboxylic acid selected from the group consisting of diglycolic acid, saturated aliphatic dicarboxylic acids containing from 4 through 12 carbon atoms, aromatic carbocyclic dicarboxylic acids and alpha, beta-ethylenically unsaturated dicarboxylic acids and anhydrides thereof, lower alkyl esters and amides thereof, with a polyalkylene polyamine selected from the group consisting of 1,4-bis-(3-aminopropyl) piperazine, 1-(2-aminoethyl) piperazine and polyalkylene polyamines of the formula ##EQU5## wherein R" is hydrogen, C.sub.1 -C.sub.12 alkyl, or C.sub.1 -C.sub.12 hydroxyalkyl; n is an integer 2 through 6 and x is an integer 1 through 4, in a mole ratio of polyalkylene polyamine to dicarboxylic acid of from about 0.9:1 to about 1.2:1 to form a polyaminopolyamide and reacting the polyaminopolyamide with epihalohydrin in a mole ratio of epihalohydrin to amine groups of said polyaminopolyamide of from about 0.1 mole to about 2 moles, said nitrogen compound having the formula RRR'N wherein R is independently selected from the group consisting of hydrogen and C.sub.1 -C.sub.4 alkyl and wherein R' is selected from the group consisting of hydrogen, hydroxyl and C.sub.1 -C.sub.4 alkyl, and said reaction between (1) and (2) being carried out at a temperature of from about 0.degree. C. to about 150.degree. C. and until substantially all epoxide moieties of the base resin have reacted with the nitrogen compound.
- 2. The resin of claim 1 wherein the nitrogen compound is ammonia.
- 3. The resin of claim 1 wherein the nitrogen compound is ethyl amine.
- 4. The resin of claim 1 wherein the nitrogen compound is dimethyl amine.
- 5. The resin of claim 1 wherein the nitrogen compound is hydroxyl amine.
- 6. The resin of claim 1 wherein the base resin is a polyaminopolyamide--epichlorohydrin resin, the amount of nitrogen compound is from about 2 times to about 40 times the amount required for stoichiometric equivalence of the epoxide moieties, and reaction temperature is from about 50.degree. C. to about 100.degree. C.
- 7. The resin of claim 6 wherein the nitrogen compound is ammonia.
- 8. The resin of claim 6 wherein the polyaminopolyamide moiety of the polyaminopolyamide--epichlorohydrin resin is the reaction product of adipic acid and diethylenetriamine.
- 9. The resin of claim 7 wherein the polyaminopolyamide moiety of the polyaminopolyamide--epichlorohydrin resin is the reaction product of adipic acid and diethylenetriamine.
