    摘要: PROBLEM TO BE SOLVED: To provide a method for producing fluorine-containing polyether carboxylic acid amide the one molecular terminal end of which is a chemically-inactive perfluoroalkyl group and the other molecular terminal end of which is modified with a heterocyclic compound group containing a nitrogen atom.
    SOLUTION: When the fluorine-containing polyether carbonyl fluoride represented by general formula: C
    n F
    2n+1 O(C
    3 F
    6 O)
    m RfCOF (wherein Rf is a 1-2C fluorocarbon group; n is an integer of 1-3; m is an integer of 10-30) is reacted with a nitrogen-containing heterocyclic amine compound ArNH
    2 (wherein Ar is a nitrogen-containing heterocyclic compound group), the reaction temperature is raised to 80-100°C and then the reaction temperature is raised within temperature rising width where the raised temperature after 48 hours is kept within 3-5°C to perform the reaction, and the fluorine-containing polyether carboxylic acid amide represented by general formula: C
    n F
    2n+1 O(C
    3 F
    6 O)
    m RfCONHAr (wherein Rf, Ar, n and m are each as defined above) is produced.
