摘要: A bis-o-aminophenol has a formula I These bis-o-aminophenols permit the preparation of polybenzoxazoles stabilized at high temperatures. The bis-o-aminophenols are preferably prepared from the corresponding diols, which are first nitrosated. The nitroso compound is then reduced to the amino compound by hydrogenation with Pd/C and H2.

摘要: A method is described here for the layerwise construction of models, wherein, in a building region, a particulate material is applied layerwise and selectively cured. These steps are repeated until a desired model is obtained. The material comprises in this case a particulate building material and a spray-dried alkali metal silicate solution. Selective activation of the curing proceeds using a water-comprising solution.
