Mikroemulsionen aus drei unmischbaren Flüssigkeiten, die einen Perfluorpolyäther enthält.

摘要

Microemulsions substantially consisting of : - an aqueous solution, - a perfluoropolyether having perfluoroalkyl end groups, - a hydrocarbon compound, - a fluorinated surfactant and optionally also of a hydrogenated or fluorinated alcohol, said microemulsions being in the form of a limpid or opalescent liquid, macroscopically consisting of a single phase, stable in a certain temperature range. The dispersing phase (or continuous phase) in the microemulsion may consist of one of the three abovesaid liquid components, wherefore the microemulsion may be of the oil-in-water or water-in-oil type.
