  "id": "MLC-T-CHM-010212",
  "term": "Reptation",
  "field": "Chemistry",
  "definition": "A model describing the motion of long, entangled polymer chains in a dense melt or concentrated solution, where a chain moves primarily by sliding along a 'tube' formed by its surrounding chains. This snake-like motion is a key mechanism for viscoelasticity in entangled polymer systems.",
