FIELD: chemistry.
SUBSTANCE: method of producing polyorganosiloxanes includes acidosis of organoalkoxysilanes and/or mixtures thereof in the presence of acid catalysts at 75-85°C, characterised by use of phenyl-containing branched polyorganosiloxanes with terminal hydroxy and alkoxy groups, including phenyl-containing resins and industrially produced lacquer based thereon, as raw materials in addition to or instead of alkoxysilanes.
EFFECT: disclosed method enables to obtain a wide range of polyorganosiloxanes with improved properties, which are ecologically clean, competitive in terms of price, obtained using ecologically clean abundant raw material which does not contain chloride ions, and stable in granular or powder form in both solvents and without solvents.
