Abstract
An iodine-containing fluoropolyether represented by the following general formula [I]:RfO[CF(CF)CFO]CF(CF)(CH)I  [I](where Rf is a perfluoroalkyl group having 1-3 carbon atoms, m is an integer of 0-10, and n is an integer of 3-12), is a novel compound having a perfluoropolyetheralkyl group capable of giving a flexibility to the molecule chain through the etheral bond, said perfluoropolyether alkyl group being bonded to the alkyl iodide having an alkyl group having 3 or more carbon atoms, and can be produced by reaction of a fluoropolyether group-containing alcohol represented by the following general formula [II]:RfO[CF(CF)CFO]CF(CF)(CH)OH  [II](Where Rf, m, and n have the same meanings as defined above) with a metal iodide, preferably potassium iodide.
