Oil-in-water emulsion breaking with hydrophobically functionalized cationic polymers
 A method of breaking an oil-in-water emulsion which comprises the steps of treating said oil-in-water emulsion with at least a de-emulsifying amount of a water dispersible terpolymer formed by polymerization from an acrylamide monomer, a water soluble cationic monomer and a water insoluble, hydrophobic monomer, and separating the formed water phase from the formed phase of terpolymer and the oil.
