【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Ｍｎ￣（２＋）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Ｍｎ￣（２＋）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。更多还原

【Abstract】 The ESR spectra of magnanese sulfonated cthylene-propylene-diene terpolymer（SEPDM-Mn） in mixed solvent of xylene and alcohol have been investigated．Thespectra exhibit resolved six hyperfine lines or a single broad line depending upon thesolvation extent bctween Mn^2＋ and alcohol． The aggregation state of Mn^2＋ is affectedby the coneentration of Mn^2＋_， alcohol content in the mixed solvent，molecular volumeof alcohol and temperature． All these results are consistent with those obtained fromthe viscometric behaviors of ionomer solutions更多还原
