In a polyacid consisting of polyacrylic acid attached to a polyamide matrix, marked effects in equilibrium acid–base characteristics are observed, attributable to a hindered polyelectrolyte structure. In the presence of neutral electrolyte, the very high values found for p K a drop sharply. A break in the Henderson‐Hasselbalch curve indicates a conformational transition at α = 0.55 which is deferred to 0.95 by the presence of neutral electrolyte.
