    Abstract: PROBLEM TO BE SOLVED: To provide a new and effective process for producing a W/O-type emulsion composed of a crosslinked polymer swollen in water and having decreased residual monomer content by a post-treatment using a redox initiation agent system. SOLUTION: The objective emulsion containing a crosslinked addition polymer swollen in water is produced by a post-treatment using a redox initiation agent system to decrease the residual monomer content. The post-treatment is carried out preferably by adding a redox initiation agent system compose of A an oxidizing agent of the formula R1OOH (R1 is H, a 1-8C alkyl or a 6-12C aryl) and/or a compound releasing hydrogen peroxide in an aqueous medium in an amount of 0.001-5 wt.% based on the total monomer, (B) an α-hydroxycarbonyl compound of the formula (R2 is H or a 1-12C alkyl; R3 is H, OH, a 1-12C alkyl, or the like) and/or a compound releasing the above compound in an aqueous medium in an amount of 0.005-5 wt.% based on the total monomer and (C) a catalytic amount of a polyvalent metal ion.
