| 摘要 |
Thermally stable functionalized organosilicon compounds containing at least one activated azo group, of formula (I): [(G0)3SiO1/2]m[(G0)2SiO2/2]n[G0SiO3/2]o[SiO4/2]p[(G2)a(G1)a'(Z-CO-HN-NH-CO-A)SiO(3-a-a')/2] are synthesized from at least one hydrazino precursor (II) (-HN-NH-) of the compound (I), oxidizing the precursor (II) into an azo group for the compound (I), employing an oxidizing system including at least one oxidizing agent (Ox) and at least one base (B), such oxidizing being carried out in a two-phase aqueous/organic medium and such that the pH of the aqueous phase ranges from 3 to 11.
