✦ Synopsis

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 pK. drop sharply. A break in the Henderson-Hasselbalch curve indicates a conformational transition a t a = 0.55 which is deferred to 0.95 by the presence of neutral eleat,rolyte.
