| 20080255325 | Process for the Continuous Preparation and Isolation of Soluble Preceramic Oligomers and/or Polymers - The invention relates to a method for continuously producing pre-ceramic polymers. The inventive method consists in synthesising polymers, in separating polymers from a reaction mixture and in thermally conditioning for defining a cross linkage degree and Theological properties, wherein all said steps are integrated into a single method. The thus obtainable polymers are used in the form of an initial material for producing non-oxidised ceramics in ternary X/Y/N or X/Y/N/C quaternary systems. Said materials are characterized by the high mechanical, thermal and chemical resistance thereof, wherein any X and Y combination can represent in particular Si, B, P, Al, Ti, V, Zr, Ta elements. | 10-16-2008 |
| 20090030157 | Method for the Continuous Production of Mono-, Oligo- and/or Polyborosilazanes that Contain Carbon - The invention relates to a device and a method for producing mono-, oligo- and/or polyborosilazanes that contain carbon. According to said method (i) a one-component precursor compound is reacted with ammonia or an organic amino in an aminolysis step, (ii) a reaction mixture is extracted at least once from the aminolysis in a continuous extraction step using an organic solvent, (iii) ammonia or a phase containing organoamine that accumulates during the extraction process is discarded, recovered or at least partly recirculated and (iv) mono-, oligo- and/or polyborosilazanes containing carbon are obtained from the extraction phase containing the solvent. | 01-29-2009 |
