Boron nitrogen polymers are obtained by heating in a closed system at 350 DEG to 600 DEG C. a plurality of different borazoles each having the formula <;FORM:1012317/C3/1>; where Y1, Y2 and Y3 each represent a hydrogen atom, a hydrocarbon group free from non-aromatic unsaturation or a dimethyl-s-triazinyl group; and X1, X2 and X3 each represent a hydrogen atom, a hydrocarbon group free from non-aromatic unsaturation, a dimethyl-s-triazinyl group or a tertiary amino group which is free from non-aromatic unsaturation and consists, apart from the amino nitrogen atom, of only carbon and hydrogen atoms. Examples describe polymerizing mixtures of (1), (2), (4) and (5) B-triphenylborazole and hexamethylborazole, B - triphenyl - N - trimethylborazole or N-trimethylborazole; (3) B-triphenyl-N-trimethylborazole and hexamethylborazole.;FORM:1012317/C3/1>
