    摘要： A (meth)acryloyloxy-containing organosilicon compound (3) is prepared by simultaneously feeding a hydrohalosilane compound (1) and a (meth)acrylate compound (2) in the presence of a polymerization inhibitor to a reaction system, and effecting hydrosilylation reaction in the presence of a platinum catalyst. The content of (meth)acrylate compound (2) is 0-100 mol % based on the content of organosilicon compound (3) in the reaction system. R is a C1-C10 monovalent hydrocarbon group, X is halogen, n is 1, 2 or 3, R2 is H or methyl, and R3 is a C1-C18 alkylene group.
