Summary Light scattering measurements on a number of samples of potassium polyphosphate dissolved in 0.1 M NaBr solution in water were made. With fair approximation, the second virial coefficient was found to be inversely proportional toM w 0.5 (M w = Weight-average Molecular Weight). In conjunction with intrinsic viscosities, the values ofM w were used in calculating the radius of gyration, $$\langle \overline {_S 2} \rangle ^{\tfrac{1}{2}}$$ . The ratio $$\langle \overline {_S 2} \rangle ^{\tfrac{1}{2}} /M_w^{\tfrac{1}{2}}$$ was found to be constant indicating that potassium Kurrol Salt exists as random coils in solutions. The average value of Flory constant calculated with the help of the available data was found to be 1.96 × 1021 which is quite close to that predicted by Flory.
