FIELD: chemistry.
SUBSTANCE: invention relates to the chemical technology of organosilicon polymers. Proposed atr phenyl-containing nanogels of the general formula [R(CH3)(C6H5)SiO0,5]i[SiO2]m, where R refers to -CH3 and m takes any value from 3 to 4 or R refers to -C6H5 and m takes any value from 1 to 4. A method for their preparation is also proposed, including the polycondensation of a 30% solution of tetraethoxysilane and alkoxysilane of the general formula R(CH3)(C6H5)Si(OC2H5) in a molar ratio of 1:1 to 1:4 in acetic acid at a boiling temperature of the reaction mixture.
EFFECT: technical result is the expansion of a number of organosilicon nanogels that allow to modify phenyl-containing matrices and obtain composites based on them, as well as the development of a simple and environmentally friendly method for obtaining phenyl-containing nanogels with controlled composition and properties that does not require using a catalyst and chlorine-containing reagents.
