  "term": "Kraemer equation",
  "field": "Chemistry",
  "definition": "An empirical equation for the concentration dependence of the inherent viscosity of a dilute polymer solution, meaning the natural logarithm of the relative viscosity divided by concentration. The inherent viscosity equals the intrinsic viscosity plus the Kraemer coefficient times the square of the intrinsic viscosity times the concentration. Extrapolation to zero concentration gives the same intrinsic viscosity as the Huggins equation, which instead uses reduced viscosity.",
