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.
