    Abstract: The present invention provides a surfactant composition for emulsion polymerization of which stability upon polymerization and mechanical stability of emulsion are good, in which particle has a small size, and of which viscosity may be made to low. 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 to not more than 0.1 mol L and a compound (b) represented by the formula (II) and having a CMC in the range of from not less than 1 x 10 mol L to less than 0.007 mol L , 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: R O-(A O)m-SO3M R O-(A O)n-SO3M (in the formulae, R and R are monovalent aliphatic hydrocarbon groups; A and A are alkylene groups having 2 to 4 carbons; m and n are numbers from 1 to 50; and M and M are monovalent cations).

    Abstract: Provided is a surfactant for emulsion polymerization, the surfactant providing a polymer emulsion which is highly stable during polymerization and ensures that a polymer coating film produced from the produced polymer emulsion has good properties and also providing a polymer emulsion having good mechanical stability and chemical stability and ensuring good water resistance of a polymer film. The invention provides a surfactant for emulsion polymerization, the surfactant comprising at least one type selected from unsaturated compounds having a pentenyl group to which an alkylene oxide is added and represented by the formula (I) , (II) or (VI). The invention also provides a method of producing a polymer emulsion, the method comprising performing emulsion polymerization using this surfactant composition. wherein A represents an alkylene group having 3 to 18 carbon atoms or an alkoxymethylethylene group (alkoxy group has 4 to 18 carbon atoms), EO represents an oxyethylene group, a denotes a number of 0 to 50, b denotes a number of 0 to 200 wherein a and b are not 0 at the same time and M represents a cation; wherein A'O represents an oxyalkylene group having 3 to 18 carbon atoms, E'O represents an oxyethylene group, m denotes a number of 0 to 50 and n denotes a number of 5 to 200, provided that the - (A' O) -groups m in number Ä-(A' O)m-Ü may be the same as or different from one another.
