合成了一系列离子浓度不同的磺化聚苯乙烯钠盐和锌盐离聚体,用红外光谱考察了经不同冷却速率处理后的离聚体结构。所得结果表明,冷却速率越快,离子簇越难形成。冷却速率对钠盐和锌盐离聚体离子簇形成影响的差异可用它们偶极-偶极运动对温度的敏感性不同来解释。高离子浓度的离聚体在584cm-1出现的新吸收带被认为是与离子簇内受限聚苯乙烯链形成的某种构象规整性有关
A series of sulfonated polystyrene sodium salts and zinc salt ionomers with different ion concentrations were synthesized. The structure of the ionomers treated by different cooling rates was investigated by infrared spectroscopy. The results show that the faster the cooling rate, the harder it is for the ion clusters to form. Differences in the effects of cooling rates on the ion cluster formation of sodium and zinc ionomer clusters can be explained by their different sensitivity to temperature for dipole-dipole motion. The new absorption bands that occur at 584 cm -1 for high ion concentration ionomers are thought to be related to some conformational regularity formed by the restricted polystyrene chains in the ion cluster
