Abstract

Cationic 2-hydroxypropyltrimethyl ammonium chloride chitosan (HACC) and anionic carboxymethyl chitosan (CMC) were synthesized from chitosan according to the modified literature description. FTIR and¹H-NMR were used to demonstrate the structures of chitosan de-rivs. The degree of HACC quaternization was studied by conductomet-ric titration (DQ = 1.15), and the degree of CMC substitution by¹H-NMR (DS = 1.0, where the ratio of mono-O: mono-N derivatives was 0.7:0.3). Their coacervative properties in the aq. environment were studied. The substances showed hydrogel-like properties and were recommended as water-absorbing additives to mineral fertilizers.
