  "term": "Branch point",
  "field": "Chemistry",
  "definition": "A specific atom or group of atoms within a polymer chain from which at least three polymer chains emanate. This structural feature is responsible for the formation of branched or cross-linked polymer architectures. The presence and density of branch points significantly influence the material's physical properties, such as viscosity and elasticity.",
