Abstract
A composition that is or comprises a phosphorus-, perfluoropolyether-, and perfluoroalkyl-containing compound is provided. The compound comprises either (i) mono- or polyalkylene oxide linking groups between the phosphorus and the fluorocarbon group, or (ii) no linking group between the phosphorus and fluorocarbon group, or (iii) individual mixtures of (i) and (ii); and the fluorocarbon group can be the perfluoropolyether or perfluoroalkyl group. The compound can also be a partially esterified phosphate, a partially esterified phosphonate, a salt of a partially esterified phosphate, a salt of a partially esterified phosphonate, or mixtures of two or more thereof.
Claims45
A phosphorus-, perfluoropolyether-, and perfloroalkyl-containing compound comprising either (i) mono- or poly-alkylene oxide linking groups between the phosphorus and the fluorocarbon group, or (ii) no linking group between the phosphorus and fluorocarbon group, or (iii) individual mixture of (i) and (ii);
- said compound does not contain an aryl or arylene group;
- and said fluorocarbon group is said perfluoropolyether or perfluoroalkyl group.
A composition comprising a phosphorus-, perfluoropolyether-, and perfluoroalkyl-containing compound and optionally a thickener wherein said compound is the same as that disclosed in claim 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 1516, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, or 32.
