Emulsions of hydrocarbons and water and/or alcohol, and emulsifying preparations therefor.

摘要

The emulsions contain, as emulsifier, a polyether- polystyrene block copolymer in which the polyether block is optionally esterified. The polyether block, which is preferably polyethylene oxide, may be replaced by a polymer of a polar vinyl monomer, orthe polystyrene block may be replaced by a conjugated diene block. The emulsion preferably contains a coupling agent which is soluble in the continuous phase and couples with the part of the emulsifier solvated by the continuous phase.

The emulsifying preparation comprises an emulsifier and a coupling agent (both as described above). The coupling agent is preferably a butadiene-styrene copolymer.
