Viscosity behaviour of amylose sulfate, a strong polyelectrolyte, in water has been examined in a low concentration range. The effect of added salts on the viscosity of amylose sulfate solution is also reported. Isoionic dilution experiments have been carried out to determine the degree of ionization of the polyelectrolyte. The experimental results showed that a) the polymer is a strong electrolyte, b) the amylose backbone chain is more flexible than the cellulose backbone chain, c) the polyion size increases on dilution, d) the degree of free ions is dependent on the polyelectrolyte concentration, and e) Katchalsky cylinderical cell model is adequate for amylose sulfate chains.
