Abstract

See full text

Provided are low-viscosity aqueous compositions comprising compounds of Formula (III) and (IV). These compositions are prepared by jointly ethoxylating a mixture of the compounds of the Formula (I) and (II) to give an intermediate which represents a mixture of compounds of Formulas (I*) and (II*). The intermediate is then converted by sulfation or phosphation and subsequent neutralization, into an aqueous composition comprising the compounds of Formula (III) and (IV). The aqueous compositions are notable for having, at 20° C., a Brookfield viscosity of 3000 mPas or less (measured at 20° C. with spindle 2 and 20 rpm), and are suitable as emulsifiers for emulsion polymerization.
