“…13 Crosslinking had the same effect on the reaction of PAS with glycidol (Scheme 2). The maximum degree of hydroxyalkylation for the crosslinked polymer was achieved with a higher molar excess of glycidol and a higher dispersion as compared to those in noncrosslinked PAS (Table I) 32 and signals of carbon atoms of N-substituted 3-aminopropanediol-1,2 with chemical shifts at 54 ppm (C7), 63 ppm (C8), and 70 ppm (C9).…”

“…Solid-state 13 C-NMR spectra (126 MHz) were recorded with methods of cross-polarization with rotation at the magic angle (cross-polarization/magic angle spinning) on a Bruker Avance-500 spectrometer with a rotor diameter of 4 mm and a rotation frequency of 5000 Hz. High-resolution 1 H-NMR spectra were recorded on the Bruker Avance-500 spectrometer at 70 8C to increase the solubility of the samples and to obtain better spectral resolution.…”

Hydroxyalkyl derivatives of polyaminostyrene (PAS), polyallylamine (PAA), and polyethyleneimine (PEI) containing a 2,3-dihydroxypropyl moiety with a high degree of modification were synthesized. The chemical structures of the polymer transformation products were characterized with elemental analysis, Fourier transform infrared spectroscopy, 1 H-NMR spectroscopy, and 13 C-NMR spectroscopy in the solid state. PAS reacted with glycidol and formed poly[N-(2,3-dihydroxypropyl)aminostyrene] with a high degree of functionalization. PAA revealed primarily the graft polymerization of glycidol. In the case of PEI, primary amino groups allowed the formation of an N-derivative of 3-aminopropanediol-1,2. The PAA-based sorbent showed a high sorption capacity toward boron ions in both acidic and alkaline media. From the sorption isotherm data, the maximum sorption capacity of this sorbent at pH 4 was determined to be 3 mmol/g. The PAS-based resin maintained a high capacity between pH 9 and 12; the optimum pH was 12. The sorption capacity was 1.7 mmol/g.
