  "id": "MLC-T-CHM-001456",
  "term": "Bowtie entanglement",
  "field": "Chemistry",
  "definition": "A specific type of topological entanglement that can occur between polymer chains, characterized by a loop of one chain passing through two loops of another chain. This complex interpenetration contributes to the viscoelastic properties of polymer melts and solutions. It is a more intricate form of entanglement than simple threading.",
