| Popis: |
The fraction of carbonyl groups bound by H-bonds in aqueous solutions of some water-soluble polymers has been determined, using a method based on the previously found features of changes in chemical shifts of the carbonyl carbon 13C due to substituent variations and to H-bond formation. In addition calculated and experimental values of the chemical shifts were compared. In contrast to the monomer molecules that were completely bound to H2O molecules by H-bonds via the carbonyl group oxygen, only ∼70% of the carbonyl groups in the polymer molecules form H-bonds. |
