Surfactant composition for emulsion polymerization

Abstract

The present invention provides a surfactant composition for emulsion polymerization. The surfactant composition for emulsion polymerization comprises a compound (a) represented by the formula (I) and having a critical micelle concentration (CMC) in the range of from not less than 0.007 mol L−1 to not more than 0.1 mol L−1 and a compound (b) represented by the formula (II) and having a CMC in the range of from not less than 1×10−5 mol L−1 to less than 0.007 mol L−1, as essential components, and the molar ratio of the components (a) to (b) in terms of (a)/(b) is from 5/95 to 75/25: R1O—(A1O)m—SO3M1  (I) R2O—(A2O)n—SO3M2  (II) (in the formulae, R1 and R2 are monovalent aliphatic hydrocarbon groups; A1 and A2 are alkylene groups having 2 to 4 carbons; m and n are numbers from 1 to 50; and M1 and M2 are monovalent cations).
