The ratio of the
relative viscosity increment
to the mass
concentration of the polymer,
is the relative viscosity increment
The unit must be specified;
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.
