| Outline of Final Research Achievements |
Novel pH-responsive and thermos-responsive polymers, which formed unimolecular micelles, were developed. The pH-responsive polymers were synthesized by copolymerizing sodium 2-(acrylamide)-2-methylpropanesulfonate (NaAMPS) and pH-responsive monomers which became hydrophobic according to the increase in pH. The adsorbents, which was prepared by grafting these pH-responsive polymers on the inner surface of porous support, adsorbed or desorbed bisphenol-A, which is a representative endocrine disruptor, reversibly by pH swing. On the other hand, the thermos-sensitive polymers were synthesized by copolymerizing NaAMPS and thermos-sensitive N-isopropylacrylamide macro-monomer. These thermo-sensitive polymers formed micelles by increasing temperature, and the micelles were disrupted by decreasing temperature. From these results, the lodestar for the development of the separation system of hydrophobic endocrine disruptor was obtained.
