dormant species

synonyms: dormant macromolecule (in RDP), dormant polymer chain

https://doi.org/10.1351/goldbook.08952

Temporarily deactivated chain carrier.

Note: A dormant polymer chain can be reactivated to a propagating chain under the polymerization conditions within the timescale of the polymerization.

Example: Some dormant species are the macroinitiator in AMRP or ATRP and the macroCTA or macroRAFT agent in RAFT polymerization.
