Abstract: A process for producing a UV-stable laminated structure having thermal aging resistance includes coextruding the following layers in a single-stage operation, or laminating the following layers onto one another in a heatable roll nip: a substrate layer made up of a graft copolymer and a styrene and/or (meth)acrylate/(meth)acrylonitrile copolymer, and optionally containing a polycarbonate and a fibrous and/or particulate filler; and a transparent top layer of polymethyl methacrylate. In another embodiment, an interlayer of e.g., impact-modified polymethyl methacrylate or polycarbonate, is coextruded or laminated between the transparent top layer and the substrate layer to produce a UV-stable laminated structure. An adhesion layer containing an adhesion promoter can be coextruded or laminated on the outer surface of the substrate layer. A molding is produced by thermoforming the UV-stable laminated structure, which is advantageously backsprayed or back-cast with the substrate layer or a polyurethane foam.

Abstract: A sensor material for gases or vapors including solvent vapors, comprising at least one hydrophobic metal complex with an ion mobility or ionic concentration or optical properties, which change under the effect of the gas or vapor. These metal complexes can be applied to suitable electrode arrangements or carriers and, in conjunction with simple measuring bridges or photometers, form a sensor system for gases and vapors.
