Transient crosslink

{
  "id": "MLC-T-CHM-012222",
  "term": "Transient crosslink",
  "field": "Chemistry",
  "definition": "A non-covalent bond or physical association between polymer chains that forms and breaks reversibly under specific conditions. These temporary links arise from interactions such as hydrogen bonding, ionic aggregation, or metal-ligand coordination, in contrast to permanent covalent crosslinks. The characteristic lifetime of these reversible junctions is temperature-dependent and determines the material's viscoelastic response, including its flow and relaxation behavior.",
