Abstract
Copolymers adapted for use as stabilizers in dispersions and stable dispersions, including crosslinked dispersions containing microgel particles, prepared therefrom. Stabilizer bears pendent ethylenic unsaturation capable of reacting with monomers employed in random copolymerization used to make the dispersion polymer. Stabilizer comprises a random copolymer segment of ethylenically unsaturated monomers, some of which are characterized in that homopolymers thereof would be substantially insoluble in the organic liquid used to form the stable dispersion and some of which are characterized in that homopolymers thereof would be substantially soluble in the organic liquid used to form the stable dispersion.
