<p>A fluorinated polyether monomer represented by the formula (I) wherein Rf is C1-18 perfluoroalkyl; R is hydrogen or methyl; A1 is a linear or branched, C1-20, divalent, aliphatic group; A2 is a direct bond or a linear or branched, C1-10, divalent, aliphatic group optionally having an ether bond; X is a linear or branched, C2-5, trivalent, aliphatic group; and n is 1 to 100. It gives a fluoropolymer which serves as an active ingredient for a surface-treating agent with excellent water-and-oil repellency.</p> |
