Polyelectrolyte Titration: Theory and Experiment
Titration of methacrylic acid/ethyl acrylate copolymers is studied experimentally and theoretically. At low salt concentrations, this polyacid exhibits a plateau in the titration curve below the neutralization point. The plateau has often been attributed to a first-order phase transition associated with polymer conformational changes. We argue that the specific shape …
