Abstract: The invention concerns a synthesis method for an oligosilazane-containing condensation product comprising the following step:
conversion of oligosilazane composition with an average molecular weight of no more than 1000 g/mol,
with a dialk(en)ylamino compound of the following formula (I)
A[N(R4)2]m (I)
in which A is at least one element chosen from B, Al, Ti, Zr, and Hf, R4 is an alkyl group or alkenyl group and m is the valence of element A,
in which the reaction is run so that an average of 1.6-2.
