ABSTRACT:
A polymeric borazole is produced by reacting BCl.sub.3 and an amine at temperatures between -60.degree. C. and -5.degree. C. in an inert solvent to form an intermediate triaminoborane, and then further polymerizing the intermediate after removal of the amine hydrochloride salt via thermal condensation at a temperature in the range of 380.degree. C. to 420.degree. C. This polymer, in the form of a glassy resin, and other borazole polymers derived by the polymerization of monomers of the formula
