ABSTRACT:
A self-stabilizing dispersion composition having a copolymer having at least one polymerizable acid-containing moiety, wherein the at least one acid-containing moiety is at least partially neutralized before or during polymerization, and at least one hydrophobic moiety. A process for producing such compositions is also provided, as well as a process for encapsulating water-insoluble actives in such copolymers.
