Abstract.

The electrolytic conductivity of two electrolytes as solutions in the nonpolar solvent, n -dodecane, as a function of concentration has been studied. One was a small molecule electrolyte (tetraalkyl cation and a highly fluorinated tetraphenylborate anion), and the other was a macromolecular electrolyte (cation-containing poly(alkyl methacrylate) chain with the same anion). Two series of the macromolecular cation were prepared: one with entirely cation-containing molecules and the other with a small proportion (10%) cation-containing and the rest nonionic. The conductivity data were qualitatively similar for all systems, which formed both single ions and triple ions. The data from the two series of macromolecular electrolytes were particularly informative to understand some recent and counterintuitive electrokinetic data for particles that were stabilized by these polymers. Reducing the proportion of cationic chains in the stabilizer of the particles was found to increase their electrophoretic mobility. In the conductivity data in this study, reducing the proportion of cationic chains in solution was found to increase the magnitude of the single-ion equilibrium constant and suppress the formation of triple ions. These data should support the development of models to understand these electrokinetic results.

离子聚合物在非极性溶剂中的电解电导率。

摘要。

在非极性溶剂中作为溶液的两种电解质的电导率n已经研究了十二烷作为浓度的函数。一个是小分子电解质（四烷基阳离子和高度氟化的四苯基硼酸根阴离子），另一个是大分子电解质（含阳离子的具有相同阴离子的聚（甲基丙烯酸烷基酯）链）。制备了两个系列的大分子阳离子：一个带有完全包含阳离子的分子，另一个带有小比例（占10％）的阳离子，其余为非离子型。对于形成单离子和三离子的所有系统，电导率数据在质量上都相似。来自两个系列的大分子电解质的数据对于了解一些近期和反直觉的由这些聚合物稳定的颗粒的电动数据特别有用。发现减少阳离子稳定剂中阳离子链的比例可增加其电泳迁移率。在本研究的电导率数据中，发现减少溶液中阳离子链的比例可增加单离子平衡常数的大小并抑制三重离子的形成。这些数据应支持理解这些电动结果的模型的开发。
