  "id": "MLC-T-CHM-013048",
  "term": "Dormant species",
  "field": "Chemistry",
  "definition": "A temporarily deactivated chain carrier, that is, a polymer chain that has stopped growing but can be reactivated to propagate under the polymerization conditions. In reversible-deactivation polymerization the dormant chains are the great majority and only a small share is active at any moment. In ATRP the dormant chain end is an alkyl halide, and in RAFT polymerization it is a thiocarbonylthio group.",
