Characterization of pores and gel phase in macroporous ion‐exchange resins by means of NMR spectra

Abstract: In the NMR spectra of some types of swollen macroporous cation-exchange resins the NMR signals of the swelling liquid in the pores and in the gel phase have been resolved. From the intensities of these signals the relative volume of pores in the swollen resin was determined. The chemical shifts of the signals of the liquid in the gel and in the pores were used for the determination of the internal molality and crosslink density in the gel phase, as well as for the characterization of the quality of the pores. … Show more
