The catalyst comprises a central element, which is selected from germanium, tin and antimony, and at least one halogen atom, which is bound to the central element. A monomer having a radical reactive unsaturated bond is subjected to a radical polymerization reaction under the presence of the catalyst, thereby it is possible to obtain a polymer having narrow molecular weight distribution. The present invention has the merits such as low toxicity of the catalyst, a small amount of the catalyst can be used, high solubility of the catalyst, mild reaction conditions, no coloration, no odor (unnecessary post-treatment of molded products). The method of the present invention is more environment-friendly and economical than a conventional living radical polymerization method.Type: GrantFiled: July 24, 2006Date of Patent: July 15, 2008Assignee: Kyoto UniversityInventors: Atsushi Goto, Takeshi Fukuda, Yoshinobu Tsujii

Patent number: 7199076Abstract: In an embodiment, a method of hydrogenating a highly unsaturated hydrocarbon to an unsaturated hydrocarbon includes contacting the highly unsaturated hydrocarbon with a catalyst in the presence of hydrogen. The catalyst comprises palladium and an inorganic support having a surface area of from about 4.5 to about 20 m2/g, or alternatively 5 to 14.5 m2/g. The inorganic support may comprise ?-alumina treated with a fluoride source. The palladium may be primarily disposed near the surface of the support. In addition, the catalyst may comprise silver distributed throughout the support. In another embodiment, a method of making the foregoing selective hydrogenation catalyst includes contacting a fluorine-containing compound with an inorganic support, heating the support, and adding palladium to the inorganic support. After adding palladium to the support, the support can then be heated again, followed by adding silver to and then heating the support once again.Type: GrantFiled: December 19, 2003Date of Patent: April 3, 2007Assignee: Chevron Phillips Chemical Company LPInventors: Joseph Bergmeister, III, Tin-Tack Peter Cheung
