ABSTRACT:
New bisesters of alkenylsuccinic acids and ethylene oxide/propylene oxide block polymers, which are obtained by reaction of alkenylsuccinic anhydride of the Formula 1 ##STR1## wherein R denotes branched or unbranched C.sub.2 -C.sub.20 alkyl, with an ethylene oxide/propylene oxide block polymer of the Formula 2 ##STR2## wherein R denotes methyl or ethyl, n and m are numbers selected such that the polyethylene oxide contribution to the total molecule is 5 to 80% of the molecular weight and p is a number from 10 to 70, and their use as demulsifiers for oil-water emulsions, as corrosion-protective agents and as dispersants for dyestuffs.
