摘要： The present invention is concerned with a reactive surfactant composition for emulsion polymerization, which is able to micronize the particle diameter of a polymer emulsion and to reduce the addition amount of the reactive surfactant composition to be used. The reactive surfactant composition for emulsion polymerization of the present invention contains a reactive anionic surfactant (component A) represented by the following formula (I): wherein AO represents an alkyleneoxy group having a carbon number of 3 or more and 18 or less; EO represents an ethyleneoxy group; p represents an integer of 1 or more and 15 or less; m′ represents an integer of 0 or more; n′ represents an integer of 0 or more; M+ represents a hydrogen ion or a cation; and plural kinds of AOs may coexist.
