Patent number: 5286414Abstract: A coating composition comprising a soluble oligomer of substituted thiophenes and, where appropriate, a soluble polymer gives, applied from the solution in a dipolar aprotic solvent, highly adherent electroconductive coatings on nonconductive or semiconductive materials. In this way, films and fibers having an antistatic finish and moldings for electronics and electrics can be produced.Type: GrantFiled: May 24, 1993Date of Patent: February 15, 1994Assignee: Hoechst AktiengesellschaftInventors: Gunther Kampf, Michael Feldhues

Patent number: 5225109Abstract: The invention relates to electrically conducting polymers which are obtainable as self-supporting films or composite bodies and which contain structural units which are derived from at least one monomer of the formula (I) ##STR1## wherein R.sup.1 represents a C.sub.1 -C.sub.12 -alkoxy group and R.sup.2 represents a C.sub.1 -C.sub.12 -alkyl group. The invention furthermore relates to a process for preparing said polymers by oxidative polymerization of at least one monomer of said formula (I). The polymers according to the invention may be used, in particular, for applications for which high chemical, mechanical or thermal stability simultaneously accompanied by high electrical conductivity is necessary and of advantage.Type: GrantFiled: February 9, 1989Date of Patent: July 6, 1993Assignee: Hoechst AGInventors: Michael Feldhues, Gunther Kampf

Patent number: 5093033Abstract: The invention relates to intrinsically electrically conductive polymers, preferably oligomers, which, in the oxidized form, are completely soluble in dipolar aprotic solvents at room temperature and which contain structural units which are derived from at least one monomer of the formula (I) ##STR1## in which R.sup.1 is a C.sub.1 -C.sub.2 -alkoxy group or --O(CH.sub.2 CH.sub.2 O).sub.n CH.sub.3 with n=1 to 4 and R.sup.2 is a hydrogen atom, a C.sub.1 -C.sub.12 -alkyl group, a C.sub.1 -C.sub.12 -alkoxy group or --O(CH.sub.2 CH.sub.2 O).sub.n CH.sub.3 with n=1 to 4, or R.sup.1 and R.sup.2 together are --O(CH.sub.2).sub.m --CH.sub.2 or --O(CH.sub.2).sub.m --O-- with m=1 to 12. The invention also relates to a process for the preparation of these polymers by electrochemical polymerization of at least one monomer of this formula (I) in the presence of a conductive salt, the anode having a specific surface area of at least 0.01 m.sup.Type: GrantFiled: August 24, 1987Date of Patent: March 3, 1992Assignee: Hoechst AktiengesellschaftInventors: Michael Feldhues, Thomas Mecklenburg, Peter Wegener, Gunther Kampf

Patent number: 5066731Abstract: In electrically conducting polymers in their oxidized (doped) form, which are known per se, the anions can be exchanged in any desired manner, if the polymer in solution is brought into contact with a salt containing the anion to be exchanged and the solution equilibrium is established, taking account of the solubility product of the salts present. In this manner, the properties of the electrically conducting polymers can be adapted to different purposes.Type: GrantFiled: May 2, 1990Date of Patent: November 19, 1991Assignee: Hoechst AktiengesellschaftInventors: Michael Feldhues, Gunther Kampf, Thomas Mecklenburg

Patent number: 4860254Abstract: A volatile semiconductor memory module (RAM) is combined with a permanent memory based on an electrically polarizable, preferably ferroelectric, layer within an integrated monolithic module in such a manner that, as a result of a STORE command, the information present in the semiconductor memory is permanently stored by polarization of selected regions of the electrically polarizable layer. In the same way the permanently stored information can be read out again as a result of a RECALL command and returned to the semiconductor memory. Preferably, a ferroelectrically polarizable layer 11 is applied to the semiconductor memory, which layer, in the same way as the semiconductor memory, is provided on its upper side and underside with word and bit lines in the form of strip electrodes, 9,12. The strip electrode system 9 on the underside of the ferroelectric layer 11 simultaneously forms the word or bit line system of the semiconductor memory facing the surface.Type: GrantFiled: January 27, 1987Date of Patent: August 22, 1989Assignee: Bayer AktiengesellschaftInventors: Richard Pott, Aloys Eiling, Gunther Kampf

Patent number: 4527059Abstract: A laser activated mass spectrometer having a sample holder for holding a given component to be investigated, a laser source for producing a laser beam to evaporate the given component and a vacuum chamber in which the evaporated component is analyzed, has the sample holder and the given component mounted outside the vacuum chamber of the mass spectrometer under atmospheric pressure or in an inert gas atmosphere. The sample holder comprises a polymer carrier film for depositing the component thereon with the carrier film forming part of a wall of the vacuum chamber of the mass spectrometer. The laser beam is directed onto the deposited component for evaporating the given component and simultaneously forming a hole in the carrier film through which the given component is transferred into the vacuum chamber of the mass spectrometer simultaneously with evaporation.Type: GrantFiled: March 30, 1984Date of Patent: July 2, 1985Assignee: Bayer AktiengesellschaftInventors: Alfred Benninghoven, Gunther Kampf, Reimer Holm

Patent number: 4468468Abstract: The analysis comprises first enriching the component to be determined (target component) by contacting an non porous solid surface with the gas or the liquid to be investigated and depositing the target component from the gaseous or liquid phase onto the solid surface in the range of a monolayer preferably within the first monolayer. The deposition is effected by absorbing the target component either directly or in the form of a derivative product, which can then be detected by introducing the solid surface with the enriched target component into a mass spectrometer. Surface sensitive mass analyzers, such as secondary ion mass spectrometers or laser activated mass analyzers, have been proven successful.Type: GrantFiled: June 14, 1982Date of Patent: August 28, 1984Assignee: Bayer AktiengesellschaftInventors: Alfred Benninghoven, Gunther Kampf, Reimer Holm

Patent number: 4391522Abstract: To provide for more reliable determination of resistance of sample surfaces to light and weather influences, test apparatus is equipped with a radiation-measuring device. A portion of radiation used for testing is guided to the measuring device, by quartz guides, spectrally dispersed, and measured as to intensity and/or dosage in one or several pre-selected spectral regions. Tests may use natural or artificial radiation, and a measuring device may be stationary or movable relative to a radiation source.Type: GrantFiled: October 3, 1980Date of Patent: July 5, 1983Assignee: Original Hanau Heraeus GmbHInventors: Helmut Schmid, Martin Bock, Gunther Kampf

Patent number: 4086310Abstract: Non-porous, thin, polycarbonate films and a process for their production. Solutions of polycarbonates in concentrations of less than 5 parts solids per 100 parts solvent are applied to the surface of liquids immiscible, or sparingly miscible with, the solvent for the polycarbonate. The solvent is then evaporated, and the resultant film removed. The films are useful for the separation of gas and liquid mixtures and for electrical insulating purposes.Type: GrantFiled: March 15, 1976Date of Patent: April 25, 1978Assignee: Bayer AktiengesellschaftInventors: Ludwig Bottenbruch, Gunther Kampf, Volker Serini, Hugo Vernaleken
