  "term": "Primitive chain",
  "field": "Chemistry",
  "definition": "A conceptual representation of a polymer chain's trajectory within a dense polymeric melt or solution, where the chain is confined by topological constraints from surrounding chains. It traces the path of the polymer backbone, effectively ignoring local fluctuations and side-chain movements. This concept is central to understanding the reptation model of polymer dynamics.",
