<p>PURPOSE: To stabilize an emulsion with a small amt. of additives by preparing the aqueous microemulsion from a specific liquid perfluoropolyether, a perfluoronated surfactant and if necessary, a water-soluble electrolyte soln. CONSTITUTION: The microemulsion of an oil-in-water type or water-in-oil type is prepd. by compounding the liquid perfluoropolyether of having a mol.wt. of 1,500 to 10,000 and having a terminal group of an at least partly functionalized (non-perfluoroalkyl) type, the perfluoronated surfactant and if necessary, at least >=1 kind of the water-soluble electrolyte soln. The terminal group of the functionalized type described above is expressed by formula I (n denotes 0 or 1; B denotes a bivalent or polyvalent bondable hydrocarbon group; m denotes an integer from 1 to 3; T denotes H, COOH, SO3 H, OH or the like).</p> |
