Patent ID: 7135599

Claim:
Perfluorodiacylperoxides having the following structures: wherein: R f is —CF 3 , R f′ and R f″ are C 1 –C 3 linear or branched perfluorooxyalkyl groups; wherein: R v is selected from F, perfluorooxyalkyl, C 1 –C 3 linear or branched perfluoroalkyl; X 1 , X 2 are selected from F, perfluoroalkyl, C 1 –C 3 linear or branched perfluorooxyalkyl; wherein: n=1–3 X 3 is selected from F, C 1 –C 3 linear or branched perfluoroalkyl, with the proviso that for n=3, X 3 cannot be F; said perfluorodiacylperoxides meet the following condition: the thermal decomposition constants K d (sec −1 ) in the presence of water do not undergo substantial variations with respect to the thermal decomposition constants in absence of water.
