Evidence of Hydrogen Bonding in Chloroform and Polyacrylates from NMR Measurements

导出

摘要 The presence of hydrogen bonding in chloroform and polyacrylate mixtures was demonstrated by observation of 1H and 13 C NMR chemical shifts. Comparison of the nuclear magnetic resonance (NMR) chemical shift in polymer solutions with their low molecular mass analogues showed the effect of steric hindrance on hydrogen bonding. This initial investigation is helpful for understanding the intermolecular interaction in relatively weak hydrogen bonding polymer solutions.
