| Abstract: | Styrene/maleic anhydride copolymer-g-PEG400 hydrogels were synthesized and characterized by FT-IR.Influences of environmental pH value,temperature and ionic strength on swelling performance of the hydrogels were investigated. Especially,the dynamic swelling mechanism was studied.The(result) shows that these hydrogels can wake quick volume response to the changing of pH value,temperature and ionic strength,as some features of intelligent gel. |
