Perfluorodiacylperoxides as polymerization initiators

摘要

Perfluorodiacylperoxides having the following structures: wherein: when Rf is F, Rf', Rf'' are both -CF3; when Rf is -CF3, Rf',Rf'' are C1-C3 linear 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.
