Abstract : The viscoelastic properties of an inorganic anionic polyphosphate were studied as a function of the counterion. It is shown that as the counterion strength (as expressed, for instance by the ratio of charge to internuclear distance between cation and oxygen anion) increases, the distribution of relaxation times narrows in an approximately linear manner. A small effect of the molecular weight is also observed on the narrowing of the relaxation spectrum, but the latter is much smaller than the former. (Author)
