✦ Synopsis

Processible polymers have been prepared from borazinic derivatives. They were thermolyzed into boron nitride using an appropriate chemical and thermal treatment in order to obtain a carbon-free ceramic. Despite similar pyrolysis conditions, the crystallinity of the resulting BN was found to be di4erent for each polymer. These di4erences should be related to the structure of the molecular precursors and of the polymers derived therefrom. Polymers prepared from the borazine, (HNBH) 3 , always gave the more-crystallized materials.
