ABSTRACT:
Polymer compositions made by reacting a polyol with an aromatic hydrocarbon containing only a single reactive functionality have been discovered to be useful demulsifiers for crude oil compositions. The aromatic hydrocarbon should have at least one aryl group and only one functionality reactive with a hydroxyl. The polyol may optionally be crosslinked prior to reaction with the aromatic hydrocarbon, and the crosslinking agent may be a diepoxide.
