  "id": "MLC-T-CHM-013226",
  "term": "Junction point",
  "field": "Chemistry",
  "definition": "A specific atom or group of atoms in a polymer network where three or more polymer chains are covalently linked. These points are responsible for the network's structural integrity and elastic properties. The functionality of a junction point, meaning the number of chains emanating from it, influences the network's crosslink density.",
