Outline of Final Research Achievements

The acetylation of a nonporous cylindrical poly[tri(ethylene glycol) monomethyl acrylate-co-2-hydroxyethyl acrylate [P(TEGA-co-HEA)] gel occurred heterogeneously to give a cylindrical core-shell gel consisting of a fully acetylated shell and an unreacted core. The semi-cylindrical bilayer gel was obtained from cutting the resulting core-shell gel in two. Although the obtained bilayer gel can deform between bending and unbending in accordance with water temperature change, the gel cannot be used practically because their bending is too slow. When porous cylindrical P(TEGA-co-HEA) gels containing alcohol as a diffusion inhibitor of the acylating agents was used, the resulting semi-cylindrical acetylated P(TEGA-co-HEA) l gel can be deformed rapidly between bending and unbending in accordance with water temperature change. The interior structure of the acetylated gel and the acetylation mechanism were determined by the FTIR and EDX analyses of chloroacetated P(TEGA-co-HEA) gels.

Academic Significance and Societal Importance of the Research Achievements

代表的な感温性ゲルであるポリ(N-イソプロピルアクリルアミド) (PNIPA) ゲルは、次世代の材料として様々な応用が期待されている。しかしながら、PNIPAは生体適合性が悪く転移温度が32℃付近に固定されるという問題があり、実用化が限定されてきた。
本法では、PNIPAゲルに代わる生体適合性が高く転移温度の選択幅の広い感温性ゲルとしてポリ{オリゴ(エチレングリコール)モノアルキル(メタ)アクリート}ゲル類に着目するとともに新規の化学修飾法を提案した。本法は、化学修飾が簡便であるなど様々な特徴があり、今後の高機能感温性ゲルの合成法として有用と考えられる。
