The Huggins Equation is an empirical equation used to relate the reduced viscosity of a dilute polymer solution to the concentration of the polymer in solution.
It is named after Maurice L. Huggins.
is the intrinsic viscosity of the solution,
is the concentration of the polymer in solution.
is the specific viscosity of a solution at a given concentration.
is much smaller than 1, indicating that it is a dilute solution.
[2] The Huggins coefficient used in this equation is an indicator of the strength of a solvent.
The coefficient typically ranges from about
[3] The Huggins equation is a useful tool because it can be used to determine the intrinsic viscosity,
