用可见吸收光谱法研究了在双季铵化氨基bola型电解质存在下磺化单偶氮染料与聚乙烯吡咯烷酮的相互作用。染料与聚（乙烯基吡咯烷酮）的第一个结合常数，通过忽略与bolaform电解质的染料的结合，确定的，是远远大于那些在没有bolaform电解质。然而，在水溶液中的染料和bolaform电解质之间的相互作用被发现，使上述假设不成立。因此，染料/bolaform电解质复合物与聚乙烯吡咯烷酮的第一结合常数通过使用基于在含有染料、bolaform电解质和聚乙烯吡咯烷酮的三元体系中的平衡的方程来确定。与聚（乙烯基吡咯烷酮）的复合物的第一结合常数大于那些的染料，这表明bolaform电解质通过形成染料/bolaform电解质复合物提高染料的聚合物的亲和力。
The interaction between sulphonated monoazo dyes and poly(vinylpyrrolidone) in the presence of bolaform electrolytes with two quaternized amino groups was investigated by means of visible absorption spectrum measurements. The first binding constants of the dyes with poly(vinylpyrrolidone), determined by neglecting the binding of the dyes with the bolaform electrolytes, were much larger than those in the absence of the bolaform electrolytes. However, interaction between the dyes and the bolaform electrolytes in aqueous solutions was found, so that the above assumption was not fulfilled. Therefore, the first binding constants of the dye/bolaform electrolyte complexes with poly(vinylpyrrolidone) were determined by using the equation based on the equilibria in the trinary systems containing the dyes, the bolaform electrolytes and poly (vinylpyrrolidone). The first binding constants of the complexes with poly (vinylpyrrolidone) were larger than those of the dyes, which suggests that the bolaform electrolytes enhance the affinity of the dyes for the polymer through the formation of dye/bolaform electrolyte complexes.
