The ratio of the
relative viscosity increment to the mass
concentration of the polymer,
, i.e.
,
where
is the
relative viscosity increment.
Notes:
-
The unit must be specified;
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.
