Abstract
The present invention relates to a method for producing a water-soluble fluorine-containing vinyl ether which comprises subjecting a fluorine-containing 2-alkoxypropionic acid derivative represented by the following general formula (I):(wherein A represents —OM1 or —OM21/2, and M1 represents an alkali metal and M2 represents an alkaline earth metal; X represents a halogen atom; Y1 and Y2 are the same or different and each represents a fluorine atom, a chlorine atom, a perfluoroalkyl group or a fluorochloroalkyl group; n represents an integer of 0 to 3, and n of Y1s may be the same or different; m represents an integer of 1 to 5, and m of Y2s are the same or different; and Z represents a hydrophilic group) to thermal decomposition at a temperature of not lower than 50° C. but lower than 170° C. in the presence of a coordinating organic solvent to give a water-soluble fluorine-containing vinyl ether represented by the general formula (II):(wherein Y1, Y2, Z, n and m are as defined above),
