ABSTRACT:
Perfluorodiacylperoxides having the following structures:wherein:when Rfis F, Rf′, Rf″are both —CF3;when Rfis —CF3, Rf′, Rf″are C1–C3linear or branched perfluoro-oxyalkyl groups;said perfluorodiacylperoxides being such as to meet the following proviso: the thermal decomposition constants Kd(sec−1) in the presence of water do not undergo substantial variations with respect to the thermal decomposition constants in absence of water.
