  "id": "MLC-T-CHM-006390",
  "term": "Kuhn segment",
  "field": "Chemistry",
  "definition": "A theoretical concept representing an imaginary segment of a polymer chain that behaves as a rigid rod, statistically independent of its neighbors. It is used to simplify the description of the conformational properties of a flexible polymer chain. The length of a Kuhn segment, known as the Kuhn length, is a measure of chain stiffness.",
