| titleOfInvention | Organosilicon hydrides |
| abstract | The invention comprises organosilicon hydrides of general formula HR2SiR1SiR2H, where R is a monovalent hydrocarbon radical and R1 is a butylene radical. R may be phenyl, tolyl, naphthyl; phenylethyl, benzyl; methyl, ethyl, propyl, butyl, octyl; vinyl, allyl; cyclohexyl, cycloheptyl; cyclohexenyl and cycloheptenyl. They are obtained by reacting a diorganohalosilane of type HR2SiX with a dihalohydrocarbon of type R1X2, where R and R1 are defined above and X is chlorine or bromine, in the presence of an active metal in the temperature range 0-120 DEG C. The active metal is preferably Mg, but may be an alkali metal such as Na. Conventional organometallic reaction procedures are used. A Grignard-type reaction wherein the diorganohalosilane and the dihalohydrocarbon are reacted in the presence of Mg, or the di-Grignard of the dihalohydrocarbon is preformed, is preferred. The products may be hydrolyzed to form polymers, or the hydrolyzates may be co-polymerized with organohalosilanes or organopolysiloxanes. Hydrolytically stable oxygen-free copolymers having a repeating unit -A-R11-Si.R2-R11- where A is -R2Si.R1.SiR2-, and R11 is -CR111H-CR2111-or -R1111-CR111H-CR2111-, R111 being H or R, R being defined as above and R1111 being a divalent hydrocarbon radical, are prepared by copolymerizing hydrides of this invention with e.g. a di-alkenyl silane of formula CR2111=CR111-SiR2-CR111 =CR2111, using a chlorplatinic acid catalyst. An example is given of the preparation of 1 : 4-bis-(dimethylsilyl) butane, and its reaction with diphenyldivinylsilane to give a thermoplastic polymer with adhesive properties. |
