Patent number: 8575285Abstract: Provided is a catalyst used for a living radical polymerization method, which contains a central element consisting of carbon and at least one halogen atom binding to the central element. Further, a hydrocarbon compound can be used as a catalyst precursor. A monomer having a radical-reactive unsaturated bond is subjected to a radical polymerization reaction in the presence of the catalyst, consequently a polymer having narrow molecular weight distribution can be obtained, and thus the cost of the living radical polymerization can be remarkably reduced. The present invention is significantly more environmentally friendly and economically excellent than conventional living radical polymerization methods, due to advantages such as low toxicity of the catalyst, low amount of the catalyst used, high solubility of the catalyst, mild reaction conditions, and no coloration/no odor (no need of any post-treatments for a molded article), and the like.Type: GrantFiled: September 8, 2009Date of Patent: November 5, 2013Assignee: Kyoto UniversityInventors: Atsushi Goto, Yoshinobu Tsujii, Takeshi Fukuda

Patent number: 6468607Abstract: Disclosed is a novel liquid-crystalline compound which is a naphthalene derivative useful as an electro-optical liquid crystal display material, a liquid crystal composition containing such naphthalene derivatives and a liquid crystal display device comprising the same. The naphthalene derivative provided by the present invention exhibits an excellent liquid-crystallinity and miscibility with currently widely used liquid crystal compositions or compositions. The addition of the naphthalene derivative makes it possible to drastically lower the threshold voltage of the liquid crystal composition while maintaining its high response. The naphthalene derivative of the present invention is characterized by a large birefringence index. Further, most of the naphthalene derivative of the present invention has no strongly polar group in its molecule and thus can also be used for active matrix driving.Type: GrantFiled: April 22, 1999Date of Patent: October 22, 2002Assignee: Dainippon Ink and Chemicals, Inc.Inventors: Sadao Takehara, Masashi Osawa, Haruyoshi Takatsu, Makoto Negishi

Patent number: 6437168Abstract: A method for efficiently extracting a reaction product containing a target aromatic fluorine compound formed by the halogen exchange reaction of an aromatic chlorine compound with a fluorinating agent quickly from the reaction vessel without suffering part of the reaction product to remain as a residue inside the reaction vessel is disclosed. Specifically, the reaction product is extracted from the reactor subsequently to the halogen exchange reaction at a temperature in the range of 20-250° C. By this method, the reaction product formed in consequence of the halogen exchange reaction can be efficiently extracted quickly from the reaction vessel, and that without suffering occurrence of a residue of the reaction product.Type: GrantFiled: August 29, 2001Date of Patent: August 20, 2002Assignee: Nippon Shokubai Co., Ltd.Inventor: Kouichi Hirota
