Abstract: The chitosan/polyether semi-IPN hydrogel based on glutaraldehyde-crosslinked chitosan and polyether interpenetrating polymer network(semi-IPN) has been prepared.The physical state of water in the semi-IPN hydrogel swollen in distilled water or PH=l.25 buffer solution was studied with differential scanning calorimetry(DSC).Infrared spectroscopy was also used to provide information on the interactions of water molecules with the gel network.

Key words: chitosan polyether, semi-IPN, hydrogel, state of water, differential scanning
