Long Title: IUPAC Gold Book - degenerative chain-transfer radical polymerization
DOI: 10.1351/goldbook.08929
Status: current

Definition
Reversible-deactivation radical polymerization in which the deactivation of the radicals involves degenerative transfer (DT) of a group (or atom).

Note
Intermediate species may be present as, for example, in reversible-addition-fragmentation chain-transfer polymerization (RAFT polymerization).

Example
DT-active groups include those mentioned below under reversible-addition-fragmentation chain-transfer polymerization and certain derivatives of iodine (iodine-transfer polymerization, ITP), tellurium (organotellurium-mediated radical polymerization, TERP), antimony (organostibane-mediated radical polymerization, SBRP), or bismuth (organobismuthane-mediated radical polymerization, BIRP).
