FIELD: chemistry.
SUBSTANCE: claimed is a method of obtaining oligoborosilazanes by the interaction of oligosilazanes, which do not contain alkyl radicals at a nitrogen atom, with an aminoborane complex, which does not contain alkyl radicals at a nitrogen atom, with the ratio of silazane to a boron-containing modifier from 3 to 18, with carrying out the process at a temperature of 40-140°C in a mixture of toluene with diglyme or benzene with diethyl ether with the molar ratio from 1:1 to 1:33.
EFFECT: method makes it possible to obtain oligoborosilazanes with the given molecular weight with high output, which is reached due to the step-by-step thermal processing of the reaction mixture at an increased temperature.
