08952 IUPAC Gold Book - dormant species 10.1351/goldbook.08952 08952 current synonyms: dormant macromolecule (in RDP), dormant polymer chain 1 Temporarily deactivated chain carrier. A dormant polymer chain can be reactivated to a propagating chain under the polymerization conditions within the timescale of the polymerization. Some dormant species are the macroinitiator in AMRP or ATRP and the macroCTA or macroRAFT agent in RAFT polymerization.
