  "id": "MLC-T-CHM-002954",
  "term": "Degree-of-polymerisation dispersity",
  "field": "Chemistry",
  "definition": "A measure of the breadth of the distribution of degrees of polymerization within a polymer sample. It quantifies the heterogeneity in chain lengths among the polymer molecules. This property is often expressed as the ratio of the weight-average degree of polymerization to the number-average degree of polymerization.",
