Détermination de la viscosité intrinsèque de solutions de polymères par une simple détermination de la viscosité

By studying the molecular weights of various solutions of cis-1,4-polyisoprene the authors arrived at the formula 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.
