PROCESS FOR THE PREPARATION OF FLUOROSILICONE COMPOUNDS HAVING HYDROLYZABLE GROUPS

摘要

The present invention relates to a method for producing a hydrolyzable group-containing fluorosilicone compound. According to the method of the present invention, a hydrolyzable group-containing fluorosilicone compound can be produced from a readily available starting material by a short process. Namely, the present invention provides a method for producing a hydrolyzable group-containing fluorosilicone compound, which comprises addition-reacting a fluorine-containing unsaturated compound of the following formula A and a hydrolyzable group-containing compound of the following formula B to hydrosilyl groups of a hydrosilicone compound containing at least two units of an organosiloxane unit containing a hydrosilyl group, to form a hydrolyzable group-containing compound having a fluorine-containing organic group of the following formula a directly bonded to a silicon atom and a hydrolyzable group-containing group of the following formula b directly bonded to a silicon atom; provided that symbols in the following formulae have the following meanings: R: a monovalent polyfluorohydrocarbon group, or a monovalent polyfluorohydrocarbon group having an etheric oxygen atom, X: a bivalent hydrocarbon group, or a bivalent hydrocarbon group having an etheric oxygen atom inserted between a carbon-carbon bond, R: a hydrogen atom, a methyl group, or an ethyl group, R<10>: a monovalent organic group, Y: a hydrolyzable group, a: an integer of from 0 to 3, b: an integer of from 1 to 3, c: 2 when R is a hydrogen atom, 3 when R is a methyl group, and 4 when R is an ethyl group: R-X-CH=CHR (Y)b(R<10>)3-bSi(CH2)aCH=k2 R-X-(CH2)c- (Y)b(R<10>)3-bSi(CH2)a+2-
