Abstract: A process for endowing a polymeric article with a surface layer of an ion-conducting polymer to yield electrical surface resistivity sufficiently low for electrostatic discharge applications is provided. The polymeric article contains one or more immobilized, polymeric components having amine functional groups. The presence of the ion-conducting polymer in the surface layer lowers the surface electrical resistivity into the range suitable for electrostatic discharge applications, between about 1×105 and about 1×1012 ?/?. Plastic electrostatic dissipation materials produced by the inventive process may find use in the optical, electronics, automotive, entertainment, sporting goods, and medical sectors.

Abstract: The invention relates to a method for reducing the concentration of nitrogen oxides in waste gases released dating the production of organic amino compounds, wherein an organic compound is first reacted with NOx and/or nitric acid to form an organic nitro compound with the formation of an NOx-containing waste gas stream and the organic nitro compound is converted to the organic ammo compound by means of hydrogen-containing reaction gas, the reaction of the organic nitro compound with the hydrogen-containing reduction gas taking place with the formation of a hydrogen-containing waste gas stream, the method being characterised in that the NOx-containing waste gas stream is combined with the hydrogen-containing waste gas stream and/or an externally supplied hydrogen stream and is reacted at a temperature of 800 to 1700° C. for the at least partial reduction of the NOx concentration. The invention additionally relates to an apparatus for carrying out the method.
