Stable-radical-mediated polymerization where the initiator and dormant species are iniferters.
Examples: Well-known examples of the iniferter process are polymerizations photoinitiated by bis(dialkylcarbamothioyl) disulfides with structure
\(\ce{(R2NC(=S)S)2}\) (traditional name is tetraalkylthiuram disulfide) where the
mediating agents are dialkylcarbamothioylsulfanyl radicals (
\(\ce{R2NC(=S)S^{.}}\)) and the
dormant species are dithiocarbamates. In this case, both the bis(dialkylcarbamothioyl) disulfide and the derived dithiocarbamates can be
iniferters.
