SUMMARY stage I:
- Chemical functionalization protocols for pullulan were developed and optimized, using selective oxidation methods.
- Depending on the selectivity of the oxidizing agent (TEMPO – for the oxidation of primary hydroxyl groups, NaIO4 – for the oxidation of secondary hydroxyl groups, TEMPO in combination with NaIO4 – for the simultaneous or two-step oxidation of primary and secondary hydroxyl groups) carboxylic, aldehyde and/or aldehyde and carboxylic groups were introduced into the pullulan structure, groups that will act as active sites for the preparation of hydrogels.
- The structure of the oxidized materials was confirmed by FTIR and NMR spectroscopy.
- All indicators set out in the "project implementation plan" were achieved: 1 published paper (0 proposals), creation of the project website.
