METHYL-(HEXAFLUOROALKYL)-DICHLOROSILANES FOR SYNTHESIS OF THERMO- AND OIL-GASOLINE-STABLE FLUORO-CONTAINING SILOXANE POLYMERS

摘要

FIELD: organic chemistry. SUBSTANCE: invention proposes methyl-(hexafluoroalkyl)-dichlorosilanes of the general formula: Rf(CH3)SiCl2 where Rf - synthesized by hydroxylation reaction of the corresponding hexafluoroolefins with methyldichlorosilane in the presence of Spier platinum catalyst. Invention can be used in the industry of synthetic rubber for production of fluoro-containing siloxane polymers. EFFECT: high thermo- and oil-gasoline-stability of siloxane polymers. 1 tbl
