ABSTRACT:
Emulsions of hydrocarbon liquids such as automotive distillate and water, or water and alcohols, are formed using an emulsifier which is a block copolymer of ethylene oxide type monomers and styrene type monomers. The stability of the emulsions is improved by the addition to the emulsion of a coupling agent which is soluble in the continuous phase of the emulsion and will couple with that portion of the emulsifier which is solvated by the continuous phase of the emulsion. Preferred coupling agents for water in oil type emulsions are copolymers of butadiene and styrene.
