FIELD: chemistry.
SUBSTANCE: process for preparing soluble in organic solvents of Polymethylsilsesquioxanes Methyltrialkoxysilanes hydrolytic polycondensation of the general formula MeSi (OAlk)3, where in Alk represents C1-C3 alkyl, in a closed system at a temperature of 50-180°C and a pressure of 0.1-0.2 MPa.
EFFECT: possibility of obtaining soluble in organic solvents Polymethylsilsesquioxanes containing a large amount of OH groups of the available Methyltrialkoxysilanes under mild conditions.
