Abstract
Stable amphoteric aqueous dispersions of synthetic polymers obtained by reacting at least one unsaturated nitrogen compound capable of being hydrolyzed in an acid or alkaline medium with an aqueous emulsion reaction mixture, containing cationic species, of at least one non-ionic monomer capable of being copolymerized with the nitrogen compound to form synthetic polymers and at least one substance which generates cationic species capable of chemically binding with the synthetic polymers.
