ABSTRACT:
A method of breaking oil-in-water emulsions involving treating such oil-in-water emulsions with a polycationic water-soluble condensation copolymer. Treatment with the copolymer transforms the emulsified oil particles into flocs which may be directly removed or which may be removed after the addition of one or more flocculants.
