Abstract：
 Synthesis of warm sensitive aquagel from ultraviolet light radiation polymerization is carried out by adding reacting raw materials into deionized water to prepare preformed solution, laying aside under ultraviolet light radiation, exposing, polymerizing directly to prepare cross-linking polymer, putting the polymer into sorbitic extractor, extracting from boiled deionized water for 24hrs, taking it out, and drying in vacuum drier to obtain warm sensitive aquagel. Its low critical temperature varies between 30-40 Deg C. with raw material formula. It can be used for various aquagels, medicine control-releasing system, memory element switch, artificial muscle and chemical industrial separation. It achieves low cost, simple process, high efficiency and normal-temperature operation.
