Synthesis of B-triamino-N-tris(trimethylsily)borazine from the precursor B-trichloro-N-tris(trimethylsilyl)borazine is reported. Thermal condensations of the two borazines are discussed and mechanisms responsible for the results observed are postulated. A structural arrangement for the preceramic polymer obtained from B-triamino-N-tris(trimethylsilyl)-borazine is proposed. Utilization of the above polymer for fiber manufacture, application as fiber coatings, and coatings in general are described together with the transformations into boron nitride in ammonia atmosphere.
