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 defined as

${\displaystyle \eta _{inh}={\frac {\ln \eta _{rel}}{c}}}$

where c is the mass concentration of the polymer (g/dL) and ${\displaystyle \eta _{rel}}$ is the relative viscosity, which is defined as

${\displaystyle \eta _{rel}={\frac {\eta }{\eta _{0}}}}$
