Abstract
The invention relates to compounds containing carbonate groups and carbonyl groups and having the general formula ##STR1## in which R stands for a C.sub.1 -C.sub.4 -alkyl radical, an aryl radical, or a radical R.sup.1, where PA0 R.sup.1 has the following formula ##STR2## in which R.sup.2 to R.sup.6 stand for H, alkyl, OH, O-alkyl, SH, S-alkyl, halogen, N(alkyl).sub.2, or N(alkyl)(aryl) and at least one but not more than three of the radicals R.sup.2 to R.sup.6 stand for a radical of the formula ##STR3## in which A, B and C stand for alkylene, cycloalkylene, oxaalkylene, polyoxaalkylene or arylene, k and l both stand for an integer from 1 to 80, and the end group Z stands for alkyl, aryl, alkoxycarbonyl, alkoxycarbonyloxy, or aryl. These compounds are suitable for use as emulsifiers for dispersions.
