reduced viscosity

Synonym: viscosity number
of a polymer

The ratio of the relative viscosity increment to the mass concentration of the polymer, c, i.e. η i c, where η i is the relative viscosity increment.
  1. The unit must be specified; cm 3 g −1 is recommended.
  2. 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.
