Term: Huggins equation
https://doi.org/10.1351/goldbook.H02869

Definition:
The equation describing the dependence of the reduced viscosity, η i c, on the mass concentration of a polymer, c, for dilute polymer solutions of the form: \[\frac{\eta _{\text{i}}}{c} = \left[\eta \right]+k_{\text{H}}\ \left[\eta \right]^{2}\ c\] where kH is the Huggins coefficient and [η] is the intrinsic viscosity.
