Notes:
By studying the molecular weights of various solutions of cis-1,4-polyisoprene the authors arrived at the formula \documentclass{article}\pagestyle{empty}\begin{document}$$\left[ \eta \right] = \sqrt {2/c} \sqrt {\eta _{sp} - {\rm l}n\eta } _{rel} $$\end{document} which allowed the calculation of the intrinsic viscosity of the polymer solutions by a single viscosity determination. The formula was verified for different systems of polymer-solvent and the values are in accord with those obtained by extrapolation. An operating concentration of about 0.2% is recommended.
