Retardation

{
  "id": "MLC-T-CHM-010281",
  "term": "Retardation",
  "field": "Chemistry",
  "definition": "A decrease in the overall rate of polymerization due to the presence of species that react with propagating radicals to form less reactive or non-propagating species. This effect is distinct from inhibition, where polymerization is completely stopped. Retardation can be caused by impurities or intentionally added agents, and it results in a slower increase in polymer chain length over time.",
