Inherent viscosity

Inherent viscosity is the ratio of the natural logarithm of the relative viscosity to the mass concentration of the polymer. Inherent viscosity is the ratio of the natural logarithm of the relative viscosity to the mass concentration of the polymer. Inherent viscosity is defined as η i n h = ln ⁡ η r e l c {displaystyle eta _{inh}={frac {ln eta _{rel}}{c}}} where c is the mass concentration of the polymer (g/dL) and η r e l {displaystyle eta _{rel}} is the relative viscosity, which is defined as η r e l = η η s {displaystyle eta _{rel}={frac {eta }{eta _{s}}}} where η {displaystyle eta } is the viscosity of the solution and η s {displaystyle eta _{s}} is the viscosity of the solvent.
