Reversible-deactivation coordination polymerization

  "id": "MLC-T-CHM-010328",
  "term": "Reversible-deactivation coordination polymerization",
  "field": "Chemistry",
  "definition": "A reversible-deactivation polymerization whose chain carriers are coordination complexes, so propagation proceeds at a metal center while chains switch reversibly between active and dormant states. Coordinative chain-transfer polymerization is one example: a growing chain moves back and forth between the catalyst and a main-group metal alkyl acting as chain-transfer agent, and the chain held on that agent is the dormant species. The chain-transfer agent is typically a zinc or aluminium alkyl.",
