Surfactant composition, composition for emulsion polymerization, method of producing polymer emulsion, and polymer emulsion

Abstract

A surfactant composition including 95.5 mass % to 99.2 mass % of an anionic surfactant represented by formula (1) with respect to a total amount of the surfactant composition; and 0.8 mass % to 4.5 mass % of a nonionic surfactant represented by the following formula (2) with respect to the total amount of the surfactant composition; a composition for emulsion polymerization including the surfactant composition; a method of producing a polymer emulsion using the surfactant composition; and a polymer emulsion obtained by the production method using the surfactant composition: where R1 represents a linear or branched alkyl group having 8 to 15 carbon atoms, “m” represents a number of from 5 to 50, and M represents a hydrogen atom, an alkali metal atom, or an ammonium group; and where R2 represents a linear or branched alkyl group having 8 to 15 carbon atoms, and “n” represents a number of from 5 to 50.
