Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for preparing an organosilicon compound having a (meth)acryloyloxy group, comprising the steps of simultaneously feeding a hydrohalosilane compound and a (meth)acrylate compound having an alkenyl group in the presence of a polymerization inhibitor to a reaction system, and effecting hydrosilylation reaction in the presence of a platinum catalyst to form the organosilicon compound having a (meth)acryloyloxy group, the hydrohalosilane compound having the general formula (1): HSiX n R 1 3-n , (1) wherein R 1 is a substituted or unsubstituted C 1 -C 10 monovalent hydrocarbon group, X is a halogen atom, and n is an integer of 2 or 3, the (meth)acrylate compound having the general formula (2): wherein R 2 is hydrogen or methyl and R 3 is an unsubstituted C 1 -C 18 alkylene group, the organosilicon compound having the general formula (3): wherein R 1 , R 2 , R 3 , X, and n are as defined above, the reaction being effected under such conditions that the content of the (meth)acrylate compound having formula (2) accounts for 0 to 100 mol % based on the content of the organosilicon compound having formula (3) in the reaction system. 2. The method of claim 1 wherein the hourly feed rate of the hydrohalosilane compound having formula (1) is 50 to 200 mol % based on the hourly feed rate of the (meth)acrylate compound having formula (2).
