  • Temperature-responsive polymer compound and process for producing the same
    Patent number: 6956077
    Abstract: A temperature-responsive polymer and polymer material which has ester bond(s) and/or acid amide bond(s) respectively at one or more sites in the side chain and can be arbitrarily controlled by varying the side chain is provided.
    Type: Grant
    Filed: January 31, 2000
    Date of Patent: October 18, 2005
    Assignee: Amersham Biosciences KK
    Inventors: Yoshikatsu Akiyama, Kimihiro Yoshizako, Yukio Hasegawa, Teruo Okano
  • Temperature-responsive polymer compound and process for producing the same
    Publication number: 20050224415
    Abstract: A temperature-responsive polymer and polymer material which has ester bond(s) and/or acid amide bond(s) respectively at one or more sites in the side chain and can be arbitrarily controlled by varying the side chain is provided. The process for production thereof and the use thereof are also provided.

  • Separatory material with the use of stimulus-responsive polymer and separation method by using the separatory material
    Patent number: 6805793
    Abstract: A novel method for separating a target substance, for example, metal ion, drug or biological component is provided. According to the method, the surface of a packing undergoes a chemical or physical environmental change under a physical stimulus so that the interaction of a substance interacting with the target substance is reversibly changed in an aqueous solution, thus effecting separation.
    Type: Grant
    Filed: May 9, 2003
    Date of Patent: October 19, 2004
    Assignees: Japan Chemical Innovation Institute, The Agency of Industrial Science and Technology of the Ministry of International Trade and Industry
    Inventors: Kimihiro Yoshizako, Yoshikatsu Akiyama, Katsuhiko Ueno, Teruo Okano
  • Novel material for use in separation and separating method using the same
    Publication number: 20040134846
    Abstract: A separatory material comprising a composite material containing a stimulus-responsive polymer and a substance interacting specifically with a target substance, wherein said stimulus-responsive polymer undergoes a structural change upon a physical stimulus so that the interaction of said substance interacting specifically with the target substance is affected by the chemical or physical environmental change, thereby causing a reversible change in the interaction force with the target substance due to the physical stimulus, which separatory material is characterized in that said stimulus-responsive polymer has no affinity with said substance interacting specifically with the target substance.
