磺化乙丙三元共聚物(SEPDM)离聚体在二甲苯/5％正己醇混合溶剂中具有特异的粘浓关系和粘温关系,估计是由于金属离子被己醇溶剂化而影响离子间相互作用引起的,但尚未有更多的实验数据加以验证.本文用FTIR和ESR方法对SEPDM离聚体溶液作进一步考察,发现金属离子与己醇确实存在溶剂化效应,溶剂化程度与离子的大小、浓度和温度有关,它直接影响离子在溶液中存在的状态(单离子或离子聚集体),这些结果为从分子水平了解离聚体溶液性质提供了理论根据.用波谱方法研究离聚体溶液中的离子相互作用尚鲜见报道.
Sulfonated ethylene propylene terpolymer (SEPDM) ionomer in xylene / 5% n-hexanol mixed solvent has a specific viscosity relationship and viscosity, it is estimated that due to metal ions solvated with hexanol to inter-ionic But no more experimental data have been validated.In this paper, we further investigated the SEPDM ionomer solution by FTIR and ESR methods, and found that the solvation effect of metal ion and hexanol did exist, the degree of solvation and ionic Size, concentration and temperature, which directly affect the state of ions in solution (single ions or ion aggregates), these results provide a theoretical basis for understanding the properties of ionomer solution at the molecular level.Using spectral methods to study ionomer Ion interactions in solution are rarely reported.
