Abstract
The present disclosure relates to demulsifier compositions and methods of resolving emulsions using the compositions. The demulsifiers include modified hydroxy-succinimide copolymers. For example, the demulsifiers may include ethoxylated or propoxylated hydroxy-succinimide copolymers. The demulsifier compositions are useful for resolving oil-in-water, water-in-oil, and complex emulsions of water and oil.
