Degree of supercooling

{
  "id": "MLC-T-CHM-002953",
  "term": "Degree of supercooling",
  "field": "Chemistry",
  "definition": "The difference between the equilibrium melting temperature of a crystalline polymer and the actual temperature at which crystallization begins. This phenomenon occurs when a liquid polymer cools below its freezing point without solidifying. A larger degree of supercooling generally leads to a higher nucleation rate and smaller crystallite sizes.",
  "synonyms": [
    "degree of undercooling"
