Abstract

Surfactant compositions which comprise (i) 10 to 90% by weight of one or more compounds selected from the group (a) to (e), and (ii) 10 to 90% by weight of water, based on the composition, are disclosed, where the compounds (a) to (e) are defined as follows: The surfactant compositions are liquid and pourable at 20° C., with a pour point below 0° C., and are useful as emulsifiers in emulsion polymerization.
