| 摘 要： | 考察了磺化乙丙三元胶锰盐离聚体在二甲苯/正己醇混合溶剂中的ESR谱,结果表明醇对金属离子的溶剂化作用破坏了溶液中Mn2+的聚集,出现超精细分裂的ESR谱线,溶剂化程度与醇含量、醇分子体积、温度和Mn2+浓度有关,这些结果与离聚体溶液粘性行为得到的结论相一致。

| Abstract: | The ESR spectra of magnanese sulfonated cthylene-propylene-diene terpolymer (SEPDM-Mn) in mixed solvent of xylene and alcohol have been investigated.The spectra exhibit resolved six hyperfine lines or a single broad line depending upon the solvation extent between Mn2+ and alcohol. The aggregation state of Mn2+ is affected by the coneentration of Mn2+, alcohol content in the mixed solvent,molecular volume of alcohol and temperature. All these results are consistent with those obtained from the viscometric behaviors of ionomer solutions |
