Abstract
At least two monosilanes each containing one different hydrocarbon radical attached to silicon through C to Si linkages, the remainder of the silicon valencies being satisfied by hydrolysable radicals are hydrolysed and inter-condensed. Suitable hydrolysable radicals are hydrogen, halogens, alkoxy, aroxy and acyloxy. A list of suitable hydrocarbon radicals is given in the Specification. Halogenated hydrocarbon radicals may also be used. The mixture to be hydrolysed may be dropped into the theoretical quantity of water, preferably dissolved in a common solvent, e.g. alcohol, ether, dioxane, acetic acid or acetone. Acid catalysts may be present. Hydrolysis may be partial, a water-miscible solvent, absence of acid catalysts, and low temperature aiding this condition. In the examples: (1) dodecylsilicon trichloride and phenylsilicon trichloride dissolved in ethyl alcohol and "Cellosolve" (Registered Trade Mark) were hydrolysed and condensed by dropwise addition of water, removal of solvents and heating; (2) ethyl alcohol was added to mixed dodecylsilicon trichloride and phenylsilicon trichloride. After evolution of HCl had ceased, water was added dropwise and the product then heated; (3) dodecylsilicon trichloride and methyltriethoxysilane were dissolved in Cellosolve. Ethyl alcohol and water were added and the resin freed from solvents; (4) and (5) methyltriethoxysilane and phenylsilicon trichloride were heated in ethyl alcohol till evolution of HCl ceased. Water and Cellosolve were added, the mixture heated and solvents evaporated; (6) aqueous ethyl alcohol was added to a mixture of phenylethyl silicon trichloride and methyltriethoxysilane. Excess was then added and solvents evaporated; (7) a solution of benzyl silicon trichloride and dodecylsilicon trichloride in dioxane was hydrolysed and intercondensed by slow addition of aqueous dioxane; (8) is similar to (7) using phenylsilicontrichloride and dodecylsilicontrichloride; (9) a solution of benzylsilicontrichloride and methallylsilicontrichloride in dioxane was hydrolysed and intercondensed by slow addition of aqueous dioxane; (10) methyl tri-ethoxysilane and dodecylsilicontrichloride were hydrolysed and intercondensed in aqueous ethyl alcohol; (11) benzylsilicon trichloride and phenylethylsilicon trichloride were hydrolysed and intercondensed in aqueous dioxane. The products may be used as moulding compounds, film-forming coatings, varnishes, impregnating agents or embedding media for condenser plates.
