Patent number: 7199212Abstract: A novel polymerization catalyst for polyesters, which does not contain any germanium or antimony compound as the main component; polyesters produced with the catalyst; and a process for producing polyesters. This polymerization catalyst is excellent in catalytic activity, little causes thermal degradation of polyesters in melt molding even when neither deactivated nor removed, and can give thermally stable polyesters which little generate foreign matter and are excellent in transparency and color. The polymerization catalyst is one which contains as the first metal-containing component at least one member selected from the group consisting of aluminum and aluminum compounds and which gives polyethylene terephthalate (PET) having a thermal stability parameter (TS) satisfying the relationship: (1) TS<0.3.Type: GrantFiled: December 25, 2000Date of Patent: April 3, 2007Assignee: Toyo Boseki Kabushiki KaishaInventors: Takahiro Nakajima, Kenichi Tsukamoto, Shoichi Gyobu, Maki Sato

Patent number: 7101961Abstract: The present invention provides a method for preparation of poly(o-phenylenediamine) nano-belt comprising mixing aqueous solutions of o-phenylenediamine and of oxidant in a mole ratio of 1:0.1–1 under stirring; standing for 0.5–2 hrs at room temperature; and obtaining poly(o-phenylenediamine) nano-belt. The method is suitable for large-scale production. In the absence of template and surfactant, aqueous solutions of o-phenylenediamine and of oxidant are mixed in a specified mole ratio and thus obtain a poly(o-phenylenediamine) nano-belt with length of several hundred micrometers, width of several hundred nanometers and thickness of tens nanometers. The method is simple, quick and suitable for large-scale manufacture. The poly(o-phenylenediamine) nano-belt thus prepared possesses excellent semiconductor properties and is one of the most promising conductive polymer materials.Type: GrantFiled: June 10, 2005Date of Patent: September 5, 2006Assignee: Changchun Institute of Applied Chemistry Chinese Academy of SciencesInventors: Erkang Wang, Xuping Sun, Shaojun Dong

Patent number: RE40571Abstract: The present invention provides a catalyst for polyester production capable of producing a polyester with high catalytic activity, a process for producing a polyester using the catalyst and a polyester produced thereby. The catalyst comprises a solid titanium compound obtained by dehydro-drying a hydrolyzate obtained by hydrolysis of a titanium halide and which has a molar ratio (OH/Ti) of a hydroxyl group (OH) to titanium (Ti) exceeding 0.09 and less than 4. In the process, the polyester is obtained by polycondensing an aromatic dicarboxylic acid, or an ester-forming derivative thereof, and an aliphatic diol, or ester-forming derivative thereof, in the presence of the catalyst. The resulting polyester has excellent transparency and tint, a titanium content of 1 to 100 ppm, a magnesium content of 1 to 200 ppm and a magnesium to titanium weight ratio of not less than 0.01.Type: GrantFiled: September 16, 2004Date of Patent: November 11, 2008Assignee: Mitsui Chemicals, Inc.Inventors: Takeshi Ohmatsuzawa, Fujito Ehara, Hideshi Hori, Kazuo Toyota, Kenzaburou Fukutani, Junichi Imuta, Akiyoshi Shimizu, Takayuki Onogi, Seiji Noda, Masayuki Sakai, Shoji Hiraoka, Koji Nakamachi, Michio Tsugawa, Satoru Miyazoe
