Abstract:
It is to provide a compound which has a low vapor pressure and low viscosity, which is less problematic in deterioration during its use and which is useful as e.g. a lubricant, a surface modifier or a surfactant.A fluoropolyether compound represented by the formula (X—)xY(—Z)z, wherein X is a group represented by the formula HO—(CH2CH2O)a.(CH2CH(OH)CH2O)b—(CH2)c—CF2O(CF2CF2O)d— (wherein “a” is an integer of from 0 to 100, b is an integer of from 0 to 100, c is an integer of from 1 to 100, and d is an integer of from 1 to 200), Z is a group represented by the formula RFO(CF2CF2O)g— (wherein RF is e.g. a C1-20 perfluoroalkyl group having an etheric oxygen atom inserted between carbon-carbon atoms, and g is an integer of from 3 to 200), Y is e.g. a (x+z) valent perfluorinated saturated hydrocarbon group, x is an integer of at least 2, z is an integer of at least 0, and (x+z) is an integer of from 3 to 20.
