reduced viscosity

of a polymer
Synonym: viscosity number
The ratio of the @R05283@ to the mass concentration of the polymer, \(c\), i.e. \(\frac{\eta _{i}}{c}\), where \(\eta _{i}\) is the @R05283@.
  1. The unit must be specified; \(\text{cm}^{3}\ \text{g}^{-1}\) is recommended.
  2. This quantity is neither a @V06627@ 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 @V06627@ number.
