Addition-fragmentation chain transfer

  "id": "MLC-T-CHM-000229",
  "term": "Addition-fragmentation chain transfer",
  "field": "Chemistry",
  "definition": "A mechanism in chain polymerization where a propagating radical adds to a chain transfer agent, forming an intermediate radical that subsequently fragments to generate a new radical and a dormant polymer chain. This process allows for control over polymer molar mass and end-group functionality. It is a key mechanism in reversible addition-fragmentation chain transfer (RAFT) polymerization.",
