This paper proposes a convenient route to oxidize the -CH<sub>2</sub>-OH groups in the water-soluble pullulan, using a new catalytic polymer-supported <i>N</i>-hydroxyphthalimide (NHPI) immobilized on polystyrene. The protocol involves the presence of sodium hypochlorite and sodium bromide. The conversion is possible at room temperature, atmospheric pressure, and pH = 10. The characterization of both the catalysts and oxidized pullulan was done using NMR and FTIR methods. Using polyelectrolyte t ...[more]
