Abstract
An acryloxy or methacryloxy group-containing organosilicon compound of the formula (wherein Ris a substituted or unsubstituted monovalent hydrocarbon group of 1 to 10 carbon atoms, Ris a hydrogen atom or a methyl group, Ris an unsubstituted divalent hydrocarbon group of 1 to 18 carbon atoms, X is a halogen atom and n is an integer of 1, 2 or 3) is to prepared by subjecting a hydrohalosilane compound of the formulaHSiXR ()and an alkenyl group-containing (meth)acrylate compound of the formula to a hydrosilylation reaction in the presence of an acid amide compound and a platinum catalyst. This method is able to suppress, in the industrial scale production of (meth)acryloyloxy group-containing organosilicon compounds, propagation reactions by which the starting (meth)acrylate compound self-polymerizes.
