synonym: degenerate chain-transfer radical polymerization

initialism: DTRP

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).

Examples: 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).
