    Abstract: Aromatic azole compounds such as 2-(4-aminophenyl)-5-amino-benzimidazole are prepared in an organic sulfonic acid solvent instead of polyphosphoric acid. This allows recovery and recycle of the solvent and avoids the handling and environmental concerns resulting from the use of polyphosphoric acid. The resulting compounds find use in the pharmaceutical industry, as anticorrosion agents, and as precursors for high-performance fibers having high strength, stiffness, and flame resistance.

    Abstract: Provided are multilayer laminates having one or more layers comprising twisted nematic liquid crystals and one or more layers of a polymeric sheet. The twisted nematic liquid crystal layers reflect infrared radiation. Thus, the multilayer laminates are useful to reduce the transmission of infrared energy. For example, in some embodiments the multilayer laminates are useful as windows to reduce energy consumption necessary to cool the interior of a structure such as an automobile or building. Preferably, the multilayer laminates retain one or more of the beneficial properties of safety glass. The multilayer laminates may include additional layers such as infrared absorbing layers, half wave plates, and the like, to minimize the transmission of infrared energy. The multilayer laminates may also include further additional layers such as polymeric films, polymeric sheets, rigid sheets, and the like.
