Chain propagation

  "id": "MLC-T-CHM-001846",
  "term": "Chain propagation",
  "field": "Chemistry",
  "definition": "The step in chain polymerization where an active polymer chain reacts with a monomer molecule, adding it to the growing chain and regenerating the active site. This process leads to the increase in molecular weight of the polymer. The rate of propagation is a key kinetic parameter in polymerization reactions.",
