(57) [Problem] To provide a reactive surfactant composition for producing a polymer emulsion having good stability without increasing the particle size. SOLUTION: The molecule has one reactive group selected from a vinyl group, an allyl group or a group represented by the formula (1) and one anionic hydrophilic group, and has a critical micelle concentration (CMC) of 0. It has a reactive surfactant (a) of 007 to 0.4 mol / L, one reactive group and one anionic hydrophilic group, and has a CMC of 1 A reactive surfactant (b) having a content of at least 10-5 mol / L and less than 0.007 mol / L is an essential component, and the molar ratio of the components (a) and (b) is (a) / (b) = 5 / A reactive surfactant composition having a ratio of 95 to 60/40, and a method for producing a polymer emulsion using the composition.
