The ratio of the relative viscosity increment to the mass concentration of the polymer, \(c\), i.e. \(\frac{\eta _{i}}{c}\), where \(\eta _{i}\) is the relative viscosity increment.
Notes:
- The unit must be specified; \(\pu{cm3 g-1}\) is recommended.
- This quantity is neither a viscosity nor a pure number. The term is to be looked on as a traditional name. Any replacement by consistent terminology would produce unnecessary confusion in the polymer literature. Synonymous with viscosity number.
