iniferter process

https://doi.org/10.1351/goldbook.08919
Stable-radical-mediated polymerization where the initiator and dormant species are iniferters.

Note: In the iniferter process the dominant mechanism for control is stable-radical mediated polymerization (SRMP) but the control mechanism may also involve degenerate chain transfer radical polymerization.

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.
