A variety of diarylpyrazole derivatives III-VI were synthesized and structurally characterized using FTIR, 1H and 13C NMR spectroscopy, and in case of compound VIb by X-ray single crystal analysis. The in vitro biological studies rev
New developments in thermally stable polymers

Advances in high-temperature polymers since 1985 are discussed with the emphasis on the chemistry.High-temperature polymers refer to materials that exhibit glass-transition temperatures > 200 deg C and have the chemical structure expected to provide high thermooxidative stability.Specific polymers or series of polymers were selected to show how the chemical structure influences certain properties.Poly(arylene ethers) and polyimides are the two principal families of polymers discussed.Recent work on poly(arylene ethers) has concentrated on incorporating heterocyclic units within the polymer backbone.Recent polyimide work has centered on the synthesis of new polymers from novel monomers, several containing the trifluoromethyl group strategically located on the molecule.Various members in each of these polymer families display a unique combination of properties, heretofore unattainable.Other families of polymers are also briefly discussed with a polymer from an AB maleimidobenzocyclobutene exhibiting an especially attractive combination of properties.
