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. R1 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.
在聚合抑制剂存在下,将氢卤硅烷化合物(1)和(甲基)丙烯酸酯化合物(2)同时加入反应体系,并在铂催化剂存在下进行氢化硅反应,制备含(甲基)丙烯酰氧基的有机硅化合物(3)。根据反应体系中有机硅化合物(3)的含量,(甲基)丙烯酸酯化合物(2)的含量为 0-100 摩尔%。R1 是 C1-C10 单价烃基,X 是卤素,n 是 1、2 或 3,R2 是 H 或甲基,R3 是 C1-C18 亚烷基。
