Methods are disclosed relating to the use of a permeable membrane to control the release of a monomer and/or oxidant as well as a bulk polymerization method.Type: GrantFiled: October 17, 2011Date of Patent: October 23, 2012Assignee: The Ohio State University Research FoundationInventors: Arthur J. Epstein, Nan-Rong Chiou, Ly James Lee, Chunmeng Lu

Patent number: 8289677Abstract: The present invention provides a conductive polymer suspension for providing a conductive polymer material having a high conductivity and a method for producing the same, and in particular, a solid electrolytic capacitor having a low ESR and a method for producing the same. The conductive polymer suspension is produced by: synthesizing a conductive polymer by chemical oxidative polymerization of a monomer giving the conductive polymer by using an oxidant in a solvent containing a dopant consisting of a low-molecular organic acid or a salt thereof; purifying the conductive polymer; and mixing the purified conductive polymer and an oxidant in an aqueous solvent containing a polyacid component.Type: GrantFiled: July 28, 2009Date of Patent: October 16, 2012Assignee: NEC Tokin CorporationInventors: Ryuta Kobayakawa, Tomoki Nobuta, Naoki Takahashi, Yasuhisa Sugawara, Satoshi Suzuki, Toshihiko Nishiyama

Publication number: 20120259064Abstract: The invention provides new polymeric or oligomeric active agents with a biocidal effect. Such particularly advantageous polymeric or oligomeric active agents with a biocidal effect are obtainable via polycondensation of a guanidine acid addition salt with an amine mixture comprising at least one diamine and/or one triamine, wherein at least one amine is selected from the group comprising i) diamine, comprising at least one cycloaliphatic residue, and ii) dialkylenetriamine. At least one amine is hereby preferably selected from 4,4?-methylenebis(cyclohexylamine) and diethylenetriamine. Furthermore, it is favorable if the guanidine acid addition salt is guanidinehydrochloride.Type: ApplicationFiled: November 12, 2010Publication date: October 11, 2012Inventors: Andreas Greiner, Seema Agarwal, Claudia Mattheis
