FIELD: chemical industry. SUBSTANCE: described are chitosan adducts of compositions (XH)2B12H12x(4-x)H2B12H12 (I) and (XH)2B12H12x(4-x)(NH4)2B12H12 (II) wherein x(chitosan)=C6O4H11N, and O<x<4 and methods of preparation thereof. Chitosan is reacted with dedecahydro-closo-dodecaboric acid for adduct(I) followed by treatment with ammonia gas for adduct (II). Compounds are capable of being inflamed when ignited followed by rapid and complete combustion. This makes them useful as effective free burning material. EFFECT: more efficient preparation method. 7 cl, 5 dwg
