Chitosan has been reductively N-alkylated with a 6-O-substituted galactose derivative bearing an iminodiacetate residue, to give a chitosan derivative having a hydrophilic branch and a metal chelating group.The Cu(II) binding capacity of the derivative was comparable to native chitosan, but showed better ion-exchange ability.The product was water soluble, giving viscous 1percent aqueous solutions that showed decreased viscosity upon addition of Cu(II) ions. --- Key words: chitosan, derivative, chelation, solubilization, viscosity.
