intrinsic viscosity

of a polymer
Synonym: limiting viscosity number
https://doi.org/10.1351/goldbook.I03140
The limiting value of the @R05220@, $$\frac{\eta _{\text{i}}}{c}$$ or the @I03033@, $$\eta _{\text{inh}}$$, at infinite dilution of the polymer, i.e. $[\eta] = \lim _{c\rightarrow 0}\frac{\eta _{\text{i}}}{c}=\lim _{c\rightarrow 0}\eta _{\text{inh}}$
Notes:
1. This term is also known in the literature as the Staudinger index.
2. The unit must be specified; $$\text{cm}^{3}\ \text{g}^{-1}$$ is recommended.
3. 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 limiting viscosity number.
