VERFAHREN ZUR SYNTHESE EINES CHLORFREIEN, PRÄKERAMISCHEN POLYMERS FÜR DIE HERSTELLUNG VON KERAMISCHEN FORMKÖRPERN
A method for producing a polysilane includes a disproportionation reaction of a methylchlorodisilane mixture to form chlorine-containing oligosilane, a substitution reaction of the chlorine atoms contained in the oligosilane by the reaction with a primary amine and a cross-linking reaction of the oligosilanes using a chain former to form polysilanes. The obtained polysilanes are infusible and are very suitable for being spun to form green fibers and processed to form silicon carbide fibers and fiber composites. The method is characterized in that it can be carried out cost-effectively and quickly and with very high yields.
