Popis:	Relaxation Mossbauer spectra of two57Fe3+-exchanged acrylate cation-exchangers (SGK-7 and SG-1M, USSR) with various cross-linkage concentrations 2.5–16 mol.% were observed in windows of observation up to 250 mm/s. The frequencies of slow (ω≲10 s−1) intramolecular motions (displayed in Mossbauer lineshape) and the values of high frequency (ω≳10 s−1) atomic displacements (reflected in thef’ factor) decrease with the increase of cross-linkage concentration.
