Title: METHOD FOR PRODUCING FLUORINE-CONTAINING POLYETHER CARBOXYLIC ACID AMIDE
Abstract:
A method which comprises reacting a fluorine-containing polyether carboxylic acid fluoride represented by general formula: CnF2n+1O(C3F6O)mRfCOF [wherein Rf represents a fluorocarbon group having 1 to 2 carbon atoms; n represents an integer of 1 to 3; and m represents an integer of 10 to 30] with a nitrogen-containing heterocyclic amine compound ArNH2 [wherein Ar represents a nitrogen-containing heterocyclic group], wherein, in said reaction, the reaction temperature is elevated to 80-100oC and then the reaction is conducted, while elevating the reaction temperature within such a temperature-increasing range as to give a temperature difference after 48 hours of 3-5oC, to thereby produce a fluorine-containing polyether carboxylic acid amide represented by general formula: CnF2n+1O(C3F6O)mRfCONHAr [wherein Rf, Ar, n and m are each as defined above].
