Viscosity-average molar mass

{
  "id": "MLC-T-CHM-012594",
  "term": "Viscosity-average molar mass",
  "field": "Chemistry",
  "definition": "A type of average molar mass for a polymer sample, determined from intrinsic viscosity measurements. It is calculated using the Mark-Houwink equation, which relates intrinsic viscosity to molar mass. This average typically falls between the number-average and weight-average molar masses, providing insight into polymer chain dimensions in solution.",
