Abstract
Organo silicon resins are obtained by the hydrolysis and condensation of compounds of the general formula R2YSICH2SiY2R, wherein each R is an alkyl or monocyclic aryl radical and each Y is a halogen atom or alkoxy radical. The hydrolysis and condensation may be effected in the presence of other organo silicon halides, e.g. mono-, di- or tri-organo silicon halides. From 5 to 50 mol. per cent of one or more of the compounds (CH3)2YSiCH2SiY2CH3, (CH3)2YSiCH2SiY3 and C6H5SiY3, at least 50 mol. per cent thereof being (CH3)2YSiCH2Si Y2CH3, and from 95 to 50 mol. per cent of CH3HSiY2, wherein each Y has the above significance, may be hydrolysed and condensed, or from 40 to 95 mol. per cent of (CH3)2YSiCH2Si Y2CH3 may be cohydrolysed and condensed with from 60 to 5 mol. per cent of C6H5SiY3, wherein Y has the above significance. In the examples a mixture of the compounds CH3Cl2Si CH2SiClC6H5CH3, C6\H5CH3ClSiCH2SiCl2C6H5 and CH3Cl2SiCH2SiCl(C6H5)2 is hydrolysed with water to give a resin; (CH3)2ClSiCH2SiCl2CH3 and C6H5SiCl3 are hydrolysed with water in the presence of toluene, the organic layer shaken with sodium bicarbonate and concentrated to give a resin; a mixture of (CH3)2ClSiCH2Si Cl2CH3, (CH3)2ClSiCH2SiCl3 and C6H5SiCl3 are hydrolysed with water in the presence of toluene, n-butanol is then added, the organic layer shaken with sodium bicarbonate, and concentrated to a resin, the resulting resin is then heated and diluted with aromatic naphtha and toluene; a mixture of the compounds (CH3)2ClSiCH2SiCl2CH3, (CH3)2ClSiCH2SiCl3 find CH3HSiCl2 is hydrolysed with water and sodium bicarbonate in the presence of toluene to give a solution of a resin in toluene; (CH3)2ClSiCH2CiCl2CH3, (CH3)2ClSiCH2SiCl3, CH3HSiCl2 and C6H5SiCl3 are hydrolysed with water in the presence of toluene, methyl ethyl ketone is added, the reaction mixture neutralized with sodium bicarbonate and the resulting organic solution of a resin separated.ALSO:The invention comprises organo silicon compounds of the formula R2YSiCH2SiY2R, wherein each R is an alkyl or monocyclic aryl radical and each Y is an alkoxy or halogen atom, and a method of preparing these compounds by reacting a compound of the general formula RY2SiCH2SiY2R in the liquid phase with an alkyl or monocyclic aryl Grignard reagent, where R and Y have the above significance, the Grignard reagent being employed in a proportion of between 0.5 and 1.5 mols. per mol. of the silicon starting material. The group R may be from methyl to octadecyl, phenyl or tolyl. In the examples the following compounds are prepared: <FORM:0672825/IV (b)/1> The organo silicon compounds may be reacted with organo lithium compounds. Specification 672,824 is referred to.
