Term: iniferter
https://doi.org/10.1351/goldbook.08955

Definition:
Substance that combines the properties of an initiator, a reversible chain-transfer agent and a chain terminator or reversible deactivator.

Notes:
1) Some iniferters are also RAFT agents.
2) A substance that combines the properties of a photoinitiator, a reversible chain-transfer agent and a chain terminator or reversible deactivator is known as a photoiniferter.

Example: Examples of iniferters in radical polymerization are bis(carbamothioylsulfanyl)disulfides with structure <span title="substance">\(\ce{(R2NC(=S)S)2}\)</span> (traditional name is thiuram disulfide).

Example: Array
