Summary
This paper concerns a series of experimental results obtained on sodium alginates with various molecular weights. The dependence of the intrinsic viscosities [η] as a function of the ionic concentration (Cs) is discussed; the persistence length is given for Cs extrapolated to infinite. The dependence of the specific viscosity as a function of the overlap parameter C [η] is discussed; it is independent of Cs as long as Cs is lower than 0.5 M.
