Radical exit frequency

  "id": "MLC-T-CHM-009852",
  "term": "Radical exit frequency",
  "field": "Chemistry",
  "definition": "The average number of times a radical leaves a polymer particle per unit time, counted per radical present, in a dispersed polymerization such as an emulsion system. It acts as a first-order rate coefficient with units of s-1, so the total exit rate from a particle scales with the number of radicals it holds. It falls as particle size increases and sets, together with the entry frequency, the average number of radicals per particle.",
