[FTIR and fluorescence emission spectra of sulfonated PS and its ionomers].
The FTIR spectra of sulfonated polystyrene and Zn and La ionomers change with sulfonation degree and the kind of metal ion. With increasing the sulfonation degree, the stretching vibrational strength of -SO3H and -SO3 increases. Because of the interaction of polar group, the FTIR spectra around 1200 cm(-1) or so split. On the other hand, the degree of sulfonation influences somewhat on the intensity and position of fluorescence spectra of sulfonation polystyrene and its ionomers.
