The isoionic dilution method has been used to measure the intrinsic viscosity, [η], of a poly(acrylic acid) (PAA) sample as a function of neutralization degree, i , at low ionic strength, I = 1.0 × 10 M −3 . The results obtained for the counterion activity are in close agreement with Manning's theory for counterion condensation. The influence of the ionic strength, I , on [η] and on the Huggins coefficient, k ', was also examined and the exponents of the scaling laws relating these two parameters with I were found.
