(57) [Problem] An object of the present invention is to produce an aqueous emulsion containing a vinyl polymer having an acrylic functional group at at least one terminal. SOLUTION: The present invention is an aqueous emulsion of a vinyl polymer (I) having at least one group represented by the general formula 1 per molecule at a molecular terminal. —OC (O) C (R) = CH 2 (1) (wherein, R represents hydrogen or an organic group having 1 to 20 carbon atoms.) The polymer main chain of the vinyl polymer (I) Is preferably selected from a meta (acrylic) monomer, an acrylonitrile monomer, an aromatic vinyl monomer, a fluorine-containing vinyl monomer and a silicon-containing vinyl monomer. The vinyl polymer (I) is preferably produced by living radical polymerization, more preferably by atom transfer radical polymerization. |
