Catalytic chain termination

{
  "id": "MLC-T-CHM-001717",
  "term": "Catalytic chain termination",
  "field": "Chemistry",
  "definition": "A process in polymerization where a catalyst facilitates the cessation of chain growth, often by transferring a hydrogen atom or other group to the propagating species. This leads to the formation of a dead polymer chain and regenerates the catalyst. It is a termination pathway distinct from bimolecular termination in radical polymerization.",
  "subject": "Polymer",
