Patent ID: 7772443

Claim:
A process for producing an iodine-containing fluoropolyether represented by the following general formula [I]: RfO[CF(CF 3 )CF 2 O] m CF(CF 3 )(CH 2 ) n 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, which process comprises allowing a fluoropolyether group-containing alcohol represented by the following general formula [II]: RfO[CF(CF 3 )CF 2 O] m CF(CF 3 )(CH 2 ) n OH [II] 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 to react with a metal iodide.
