摘要： A process for the preparation of 3-methacryloxypropyldimethylchlorosilane by reaction of allylmethacrylate with dimethylchlorosilane in the presence of a hydrosilylation catalyst, characterized in that the reaction is carried out in the absence of a peroxide is provided. The process includes providing a first stream containing allylmethacrylate. A a second stream containing dimethylchlorosilane is provided. The streams contact in a continuous flow reactor in the presence of the hydrosilylation catalyst, thereby producing 3-methacryloxypropyldimethylchlorosilane. A product stream is continuously removed from the continuous flow reactor.

摘要： The invention relates to a process for the body-hydrophobization of substrates by means of organosilicon compounds (O) which are solid at 20°C and can be prepared by reacting one molar equivalent of silane (S) selected from among hydrocarbyltrihalosilane, hydrocarbyltrihydrocarbyloxysilane and mixtures thereof and partial hydrolysates thereof with polyhydroxy compounds (P) in such a ratio that from 0.3 to 1.3 molar equivalence of hydroxy radicals are present per molar equivalent of halo or hydrocarbyloxy radical. The invention further provides building material mixtures containing organosilicon compounds (O) and the substrates to be hydrophobicized.
