AQUEOUS FLUORINATED ACRYLATE RESIN EMULSIONS

摘要

An aqueous resin emulsion is disclosed. The emulsion is obtained by emulsion copolymerizing a monomer mixture comprising (a) an acrylic acid fluoroalkyl ester derivative, (b) an acrylic acid derivative, and (c) a polyfunctional monomer for internal cross-linking, in an aqueous medium. The emulsion shows excellent polymerization stability in emulsion copolymerization for the preparation thereof and excellent dispersion stability in an aqueous medium. The resulting emulsion retains its stable dispersed state even when dispersed in a buffer solution or physiological saline and, therefore, can advantageously be used in applications requiring dispersion stability of resin particles in an aqueous medium.
