An amphoteric polyurethane(APU) with both acid and base pendent groups was synthesized and a graft copolymer was obtained by reacting its NCO end group with OH and/or NH₂ groups of the chitosan molecules in dilute HCl solution. The IR and DSC results indicated the occurence of hydrogen bonding in the copolymer. The graft copolymer in HCl solution appeared to be a dispersion with special rheological property.
- amphoteric polyurethane,
- chitosan,
