Hard-segment phase domain

{
  "id": "MLC-T-CHM-005102",
  "term": "Hard-segment phase domain",
  "field": "Chemistry",
  "definition": "A distinct region within a block copolymer, particularly in segmented polyurethanes or polyureas, formed by the aggregation of rigid, high-melting polymer segments. These domains provide physical crosslinks and contribute to the material's mechanical strength and elasticity. They are typically responsible for the high-temperature performance of the material.",
