聚苯乙烯磺化及离子化后其红外光谱产生一系列特征变化，磺化度不同的聚苯乙烯其磺酸基团伸缩振动强度不同。磺化度的提高会引起磺化聚苯乙烯（ＳＰＳ）红外光谱的分裂。ＳＰＳ的离子化使得磺酸基团的对称性被破坏，１２００ｃｍ－１附近磺酸阴离子－Ｓ＝Ｏ基团的非对称伸缩振动吸收峰发生分裂，随着离子化引入的金属离子的不同，峰的分裂形态也不同。此外本文还就磺化聚苯乙烯及其离聚体的二氯甲烷溶液的荧光发射光谱进行了讨论，结果表明，磺化程度和离子化对聚合物的荧光发射峰的强度和位置都有一定影响。
Polystyrene sulfonation and ionization of its infrared spectroscopy to produce a series of characteristic changes, different degrees of sulfonated polystyrene sulfonic acid group stretching vibration intensity is different. Increasing the degree of sulfonation will cause the splitting of the sulfonated polystyrene (SPS) infrared spectrum. SPS ionization makes the symmetry of the sulfonic acid group is destroyed, 1200cm-1 sulfonate anion - S = O group asymmetric stretching vibration absorption peaks split, with ionization of the metal ions introduced, the peak, the peak The split form is also different. In addition, the fluorescence emission spectra of sulfonated polystyrene and its ionomer in dichloromethane were also discussed. The results showed that the degree of sulfonation and the intensity of ionization on the fluorescence emission peak of the polymer are both certain influences.
