Adjacent re-entry model

  "term": "Adjacent re-entry model",
  "field": "Chemistry",
  "definition": "A model describing the folding of polymer chains within crystalline lamellae, where a polymer chain folds back on itself and re-enters the same lamella at an adjacent position. This model suggests a high degree of order in polymer crystallization, with chain segments closely packed within the crystalline regions. It contrasts with the switchboard model, which proposes more random re-entry.",
