    摘要： A perfluoro unsaturated nitrile compound represented by the following general formula:

            CF₂=CFO(CF₂)nOCF(CF₃)CN

    is produced by reaction of chlorine or bromine to a perfluoro unsaturated carboxylic acid ester represented by the following general formula:

            CF₂=CFO(CF₂)nOCF(CF₃)COOR

    followed by reaction with ammonia, thereby converting the ester group to an acid amide group, and then conducting a dehydration reaction and a dehalogenation reaction of the resulting perfluoro unsaturated carboxylic acid amide represented by the following general formula:

            CF₂=CFO(CF₂)nOCF(CF₃)CONH₂

    in any desired sequence, and is effectively applied as a cross-linking site monomer for fluorine-containing elastomers.
