"Intrinsic viscosity is a measure of a solute's contribution to the viscosity of a solution. It should not be confused with inherent viscosity, which is the ratio of the natural logarithm of the relative viscosity to the mass concentration of the polymer. Intrinsic viscosity is defined as where is the viscosity in the absence of the solute, is (dynamic or kinematic) viscosity of the solut… " - Limiting viscosity
