ABSTRACT:
Stable amphoteric latices based on conjugated dienes formed by preparing an amphoteric aqueous dispersion of particles by reacting at least one unsaturated nitrogen compound capable of being hydrolyzed in an acid or alkaline medium with an aqueous emulsion reaction medium, containing cationic species, and polymerizing, in the aqueous dispersion, without prior neutralization of the dispersion, at least one conjugated diene or a mixture of conjugated dienes and at least one non-ionic monomer in the presence of an initiator selected from the group consisting of an uncharged initiator and a cationic-charge-generating initiator.
