Abstract
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.
Claims2
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):
- HSiXnR13-n, (1)
- wherein R1 is a substituted or unsubstituted C1-C10 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 R2 is hydrogen or methyl and R3 is an unsubstituted C1-C18 alkylene group,
- the organosilicon compound having the general formula (3):
- wherein R1, R2, R3, 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.
