✦ Synopsis

Living free-radical copolymers, prepared by reaction of hexattuoropropylene with an excess of perfluoro-2,5-diazahexane 2,5-dioxyl, catalyse the reaction 4 RFNO~2 RFNO 2 + RFN~NR F (R F = CF 3 or n-C3FT) at room temperature. Reaction of trifluoronitrosomethane at 70 ° also gives these products together with smaller quantities of perttuoro-(N-methylenemethylamine), before the catalyst is deactivated. Mechanisms for these reactions are suggested.
