POLYMERS BASED ON BORON AND NITROGEN,A PROCESS FOR PREPARING THEM AND THEIR USE

摘要

Process for the preparation of an organoboron polymer precursor of boron nitride, the said process being characterised in that (a) a mixture comprising a trihaloborane (compound A) and a compound containing at least one boron atom to which two halogen atoms are bonded directly (compound B) is reacted with b) a compound containing at least one NH2 group (compound C). …The invention also relates to the new polymers obtained by the said process.
