Term: degenerative chain-transfer radical polymerization
https://doi.org/10.1351/goldbook.08929

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 <em><a href="/terms/view/08935">reversible-addition-fragmentation chain-transfer polymerization</a></em> and certain derivatives of iodine (<em><a href="/terms/view/08930">iodine-transfer polymerization</a></em>, ITP), tellurium (<em><a href="/terms/view/08933">organotellurium-mediated radical polymerization</a></em>, TERP), antimony (<em><a href="/terms/view/08932">organostibane-mediated radical polymerization</a></em>, SBRP), or bismuth (<em><a href="/terms/view/08931">organobismuthane-mediated radical polymerization</a></em>, BIRP).
