Curable composition and process for production of organosilicon compound

Abstract

The present curable composition comprises an organosilicon compound produced by hydrolysis copolycondensation of (A) a silicon compound R 0 Si(R 1 ) n X 1 3-n [wherein R 0 represents a (meth)acryloyl group; and X 1 represents a hydrolyzable group] and (B) a silicon compound SiY 1 4 [wherein Y 1 represents a siloxane-bond forming group] under an alkaline condition at a ratio of compound (A) to compound (B) of 1:(0.3 to 1.8) by mol. The present process for producing an organosilicon compound comprises a reaction process of conducting alcohol exchange reaction of a silicon compound SiY 2 4 [wherein Y 2 represents a siloxane-bond forming group] in 1-propanol to produce a composition; and a condensation process of adding a silicon compound R 0 Si(R 1 ) n X 2 3-n [wherein R 0 represents a (meth)acryloyl group; and X 2 represents a hydrolyzable group] to the composition to perform the hydrolysis copolycondensation of the silicon compounds under alkaline conditions.
