FIELD: chemistry. ^ SUBSTANCE: invention relates to silicon-organic compounds, which can be used as anti-structuring additives and vulcanising agents in siloxane rubber mixtures. Oligomethyl-alkyl(methylhydroxy)(methylhydroperoxy)siloxanes are suggested its general formula: (CH3)3SiO[CH3RSiO]n[CH3(OH)SiO]m[CH3(OOH)SiO]l[Si(CH3)3, where R=CH3-; CF3CH2CH2-; C6H5-, 10<=m+1+n<=200, m<0.5(m+1+n), 1=(0.1-0.25)m, obtained by boiling during 0.5-3 hours in medium of polar solvent of appropriate hydride-containing oligosiloxanes with water hydrogen peroxide, taken in 1.1-5-fold molar excess relative to bind Si-H, in presence of catalytic amounts (0.1-1% mol of binds Si-H) of tertiary amine. Method of production is simple, is notable for high reproducibility of final product properties. ^ EFFECT: creation of simple and efficient method of production of olygosiloxanes, able to be used simultaneously as anti-structuring additive and vulcanising agent in rubber mixtures, ensuring high physicomechanical properties of vulcanisers and long term of mixture preservation in raw state, and elaboration of method of their production. ^ 2 cl, 1 tbl, 5 ex |
