Macromolecular Materials and Engineering, Volume 311, Issue 10, October 2026.Technical sodium carboxymethylcellulose (NaCMC) was synthesized by solvent‐free reactive extrusion, and its substitution level and heterogeneity were assessed through innovative, complementary approaches. Stoichiometric data reconciliation enabled indirect degree of substitution (DS) quantification, while centrifugation fractionation resolved distinct ...

DETERMINATION OF TETRAFLUOROBORATE BY POTENTIOMETRIC TITRATION
Вестник Кемеровского государственного университета, 2015 The new method for determination of tetrafluoroborate by potentiometric titration is presented. The method is based on the hydrolysis of the tetrafluoroborate anion in water solutions and it takes into account the appropriate correction factor.

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。
