【摘要】 用ＥＳＲ谱考察了磺化丁基橡胶锰盐（Ｍｎ－ＳＩＩＲ）离聚体在二甲苯／醇（少量）混合溶剂中的离子聚集行为。结果表明，在所考察的范围内，浓度及磺化度增大时ＥＳＲ谱的形状变化不大，这反映了离子聚集程度并没有发生明显变化；另外，极性共溶剂（醇）增多时，谱线分辨度增大，反映了离子聚集程度下降；温度升高时谱线变模糊，反映离子聚集程度增大。这些结果有力地支持了Ｌｕｎｄｂｅｒｇ等人提出的离聚体溶液粘度变化平衡式。更多还原

【Abstract】 Electron Spin Resonance(ESR)measurements on manganese-ionomers of sulfonated butyl rubber(Mn-SIIR)show that polar cosolvents such as alcohols could solvate the ionic groups and then destroy ionic aggregation. The solvation would be weakened and the ionic aggregation increased as temperature increased.These are in agreement with the results from viscosity measurements of ionomer in mixed solvents. But the content of ionicgroups in solution had no significant effect on the degree of ionic aggregation.更多还原
