Potentiometric Titration of Polyelectrolytes
Kobunshi Kagaku, 1958 グリオキシル酸による部分アセタール化ポリビニルアルコール(以下PVAGと略称) の電圧滴定実験を行い, Hermansらが指摘している関係が成立することを認めた。これよりPVAGの解離指数を決定した。ii) 滴定実験より得られる静電自由エネルギー変化から別に報告する取扱を利用して球形と仮定したときの高分子イオン半径の算出を試みた。それによればイオン半径は濃度の上昇とともに著しく減少するという結果を得た。iii) 泳動実験によって決定されるポテンシャルと滴定実験によって与えられるポテンシャルとを比較し, 両者にかなりの差異を認めた。これは前者が表面ポテンシャルを, 後者が高分子イオン内部のポテンシャルの平均値を与えているものと考えることにより一応説明された。

Chitosan–Alginate Polyelectrolyte Systems: From Classical Release Models to the D‐PARMO Framework
Macromolecular Materials and Engineering, Volume 311, Issue 5, May 2026.Classical empirical models fail to predict the dynamic in vivo behavior of chitosan‐alginate nanocarriers. Bridging this translational gap, the novel D‐PARMO framework replaces purely descriptive curve‐fitting with a mechanistically informed operational model.
