FIELD: elementoorganic synthesis.
SUBSTANCE: oligoorganosiloxanes are prepared via water hydrolysis of alkylchlorosilanes in presence of calcium chloride, wherein said alkylchlorosilanes are used in mixture with alkylhydridochlorosilanes or in mixture with alkylhydridochlorosilanes and tetraethoxysilane. Hydrolysis is carried out at total functionality of the system less than 2, calcium chloride concentration in water 20-43%, and water consumption 0.5-5.4 mol per 1 g-atom chlorine in initial monomer mixture.
EFFECT: enabled production of stable-in-storage waterproofing materials, components of antiadhesive compositions, and intermediates for synthesis of new products with useful physicochemical and working characteristics.
