ABSTRACT:
The invention relates to a method for continuously producing pre-ceramic polymers. The inventive method consists in synthesizing polymers, in separating polymers from a reaction mixture and in thermally conditioning for defining a cross linkage degree and rheological 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-oxidized 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.
