ABSTRACT:
A process for the preparation of amphoteric resinous aqueous emulsions useful for the treatment of fiber-containing products, comprising reacting an isocyanate-terminated urethane prepolymer with an excess of a polyalkylene polyamine to form a polyurethane-urea-polyamine, then partially reacting the amino groups in the polyurethane-urea-polyamine with a compound selected from the group consisting of alkyl isocyanates in which the alkyl group has 12 to 22 carbon atoms and alpha-olefin epoxides having 12 to 22 carbon atoms, thereby to introduce a long-chain alkyl group into the molecule, reacting the thus-formed product having some unreacted amino groups with a member selected from the group consisting of 1,3-propanesultone, 1,4-butanesultone, .beta.-propiolactone, .epsilon.-caprolactone and .delta.-valerolactone, thereby to render the polymer amphoteric, and mixing the resulting polymer with water.
