Abstract: The use of a nondendrimeric hyperbranched polyester and/or a polyesteramide which comprise alkenyl-substituted succinic acid units as a demulsifier for splitting oil-water emulsions. The succinic acid is substituted by at least one alkenyl group containing from 16 to 20 carbon atoms. Particular emulsions suitable for splitting are crude oil emulsions. Also, a nondendrimeric hyperbranched polyester or a polyesteramide which comprises alkenyl-substituted succinic acid units, the alkenyl group having from 16 to 20 carbon atoms. In addition to the alkenyl-substituted succinic acid units, the nondendrimeric hyperbranched polyester contains, as further units, at least trifunctional alcohols having been alkoxylated with an average of from 3 to 12 ethylene oxide units.
