PURPOSE:To provide a hydrophilic-hydrophobic thermally reversible material composed essentially of an aqueous solution of poly(acrylpiperidine), and having lower transition temperature than the know material. CONSTITUTION:The objective poly(acrylpiperidine) having a hydrophilic-hydrophobic transition temperature of 4-6 deg.C is prepared by irradiating acrylpiperidine or a proper solvent solution of acrylpiperidine with radiation, or by heating acrylpiperidine in the presence of a radical polymerization initiator. The intrinsic viscosity of the poly(acrylpiperidine) is preferably 0.01-6, espectially 0.1-3.
