| Abstract: | Sugar dihydroozaxole monomers with two free hydroxyl groups undergo acid-catalyzed polymerization to hyperbranched aminopolysaccharides Eq. (a)]. Their molecular weights were determined by the light-scattering method to be between 2.3×105 and 7.6×105. The degree of branching determined by 1H NMR spectroscopy after reaction with iPr2Si(Cl)]2O is close to the ideal value. Ts=MeC6H4SO2, CSA=10-camphorsulfonic acid. |
