METHOD FOR PRODUCING AQUEOUS EMULSION COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide a method for producing a self-stabilized aqueous emulsion composition having controlled molecular structure and broad molecule designing freedom without using an organic solvent by using a living radical polymerization technique. SOLUTION: The aqueous emulsion composition is produced by polymerizing 5-60 wt.% ethylenically unsaturated monomer containing carboxy group and 95-40 wt.% ethylenically unsaturated monomer copolymerizable with the former monomer in an aqueous medium in the presence of a compound having living radical polymerization property, adding an alkali to an aqueous dispersion of the alkali-soluble resin to dissolve the resin and polymerizing an ethylenically unsaturated compound in the presence of the produced water-soluble resin.
