REDUCING SURFACE TREATMENT AGENT, DIALYSIS MEMBRANE, AND ARTIFICIAL KIDNEY

摘要

PROBLEM TO BE SOLVED: To provide a reducing surface treatment agent having temperature responsibility which is hydrophilic when the temperature is lower than the predetermined temperature (T) which is lower than the living body temperature, and hydrophobic when the temperature is higher than T.

SOLUTION: The reducing surface treatment agent is constituted by combining lipid-soluble reducing products to a polymer material which is hydrophilic when the temperature is lower temperature than the predetermined temperature (T) being lower than the living body temperature, and hydrophobic when the temperature is higher than T. A vinyl monomer such as ethyl acrylate is polymerized in living fashion to an iniferter with light irradiation to get a star polymer as a homopolymer, and N-isopropyl acrylamide is polymerized by block polymerization to the homopolymer to obtain the polymer material. The low-temperature aqueous solution of this polymer material is added and mixed with an organic solvent solution of lipid-soluble reducing product such as vitamin E.
