Semi-rigid chain

{
  "id": "MLC-T-CHM-010736",
  "term": "Semi-rigid chain",
  "field": "Chemistry",
  "definition": "A polymer chain that exhibits a degree of stiffness or persistence length significantly greater than that of a flexible random coil, but less than that of a perfectly rigid rod. These chains have limited conformational freedom due to steric hindrance or strong intramolecular interactions. Examples include certain polyelectrolytes and liquid crystalline polymers.",
  "subject": "Polymer",
