摘要：
A perfluoro unsaturated nitrile compound represented by the following general formula: CF.sub.2 .dbd.CFO(CF.sub.2)nOCF(CF.sub.3)CN is produced by reaction of chlorine or bromine to a perfluoro unsaturated carboxylic acid ester represented by the following general formula: CF.sub.2 .dbd.CFO(CF.sub.2)nOCF(CF.sub.3)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: CF.sub.2 .dbd.CFO(CF.sub.2)nOCF(CF.sub.3)CONH.sub.2 in any desired sequence, and is effectively applied as a cross-linking site monomer for fluorine-containing elastomers.
