Electrolytic Properties of Aqueous Solutions of Polyacrylic Acid and Sodium Hydroxide. III. The Rate of Sodium Ion Exchange between Polyacrylate and Free Sodium Ions

摘要: The exchange of free sodium ions with bound to polyacrylate ion has been investigated by an electrolytic transference method. On the assumption that there is a single process, rate constants have computed and theory found provide moderately good representation data. A much better correlation obtained, however, if it assumed are two processes, one very rapid other slow. Presumably rapidly belong atmosphere while those slowly located within coiled polymer ion. distribution between these groups computed.
