  "id": "MLC-T-CHM-001860",
  "term": "Chain-transfer constant",
  "field": "Chemistry",
  "definition": "A dimensionless kinetic parameter that quantifies the efficiency of a chain-transfer agent in a polymerization reaction. It is defined as the ratio of the rate constant for chain transfer to the rate constant for chain propagation. A higher chain-transfer constant indicates a more effective reduction in polymer molecular weight.",
