In order to know basic information for preparation of sensing, extracting, or multifunctional materials, a molecularly imprinted polymer hydrogel for Bisphenol A(Bis-A) as a typical sample of environmental hormone was prepared from Nisopropylacrylamide(NiPAAm), 4-vinylprydine(4-VP), and N, N-methylenebisacrylamide (MBAAm) in the presence of radical initiator in ethanol solution at 60℃ for 24 hr. The Bis-Aimprinted hydrogel (MIGel) in water showed reversible shrinking and swelling changes on heating (40℃) or on cooling (20℃), respectively. The swelling ratios of MIGel (NiPAAm/4-VP/MBAAm/Bis-A=55/7.5/1/2.5 in molar ratio) and nonimprinted hydrogel were measured in an aqueous Bis-A solution. In addition of 10 times excess amount of Bis-A for splitting of Bis-A, the swelling ratio of MIGel was 20% lower than nonimprinted hydrogel. This result indicated that the network of MIGel memorized BisA. Furthermore, the shrinking-swelling behavior of the MIGel was investigated comparing with nonimprinted hydrogel with changing the temperature of the solution.
