1H NMR spectra of water contained in solutions of poly(N-vinylpyrrolidone) and its modification products in CDCl3

T. P. Klimova (a), T. A. Babushkina (a), and V. Yu. Khvostova (b)

1H NMR spectra in CDCl3 of poly(N-vinylpyrrolidone), epoxidized poly(N-vinyl- pyrrolidone), and products derived from the latter by modification with amino acids (glycine, β-alanine, γ-aminobutyric acid, and ε-aminocaproic acid) were examined. The 1H NMR spectra of the modified polymers contain signals for water protons due to different centers of water sorption. These signals differ in chemical shift and integral intensity and indicate a changed spatial packing of the polymer as the result of its modification.
