Abstract: Polyether-chitosan hydrogels are prepared in acetic acid solution with chitosan/polyether using glutaraldehyde as crosslinker.The effects of temperature,the mass ratio of polyether and chitosan,the concentration of crosslinker on swelling ratio are studied with the orthogonal experimental method to optimize the technological condition.The result showes that when the temperature is 45℃,polyether:chitosan is(0.4∶1.0),crosslinker’s concentration is(0.05?mol/L),and the semi-IPN has the highest swelling ration;Polyether-chitosan hydrogel is pH sensitivity.

Key words: polyether； chitosan； hydrogel； swelling ration； pH sensitivity；
