ABSTRACT:
A perfluoro-(N-vinylamine) compound containing a >NCF.dbd.CF.sub.2 group is produced from a perfluoro-compound containing a group of the general formula: ##STR1## (wherein X stands for a fluorine atom or a --OM group having an alkali or alkaline earth metal ion for M) and having connected to the group of the general formula a perfluoro-alkyl group having a total of 2 to 6 carbon atoms contained in the main carbon chain thereof by heating the perfluoro-compound at a temperature in the range of 100.degree. C. to 500.degree. C. thereby effecting conversion of the group of the foregoing general formula into the aforementioned >NCF.dbd.CF.sub.2 group.
