摘要：

To obtain further information on the hydrogen bonding of poly(vinyl alcohol) (PVA), attempts are being made to apply CP/MAS 13C NMR analyses to different PVA solutions in the frozen state. This article reports, the first results indicating the formation of intramolecular hydrogen bonding in the frozen solution state and its great dependencies on solvents and tacticities of PVA, as observed by frozen-state NMR spectroscopy. These results further support the previous assignment for the formation of intramolecular hydrogen bonding.
