Isoionic dilution of sodium polystyrenesulfonate in 2‐ethoxyethanol–water mixture containing 25 mass% of 2‐ethoxyethanol at 313.15 K at the total polyelectrolyte concentrations indicated has been used to determine the intramolecular contribution to the reduced viscosity and the Huggins constant, which helps interpret the coiling/uncoiling and thermodynamic behaviour in these solutions.
