Silyl (meth)acrylate compound containing a siloxy group having a bulky substituent and its production method

摘要

A silyl (meth)acrylate compound containing a siloxy group having a bulky substituent is provided. The compound is represented by the following general formula (1):; wherein R¹ and R² are independently a C_3-10 monovalent branched hydrocarbon group having a hydrocarbon group at α or β position or a monovalent C_3-10 cyclic hydrocarbon group; R³, R⁴, and R⁵ are independently an unsubstituted or substituted C_1-20 hydrocarbon group or a siloxy group represented by the following general formula (2):—OSiR⁷R⁸R⁹  (2)wherein R⁷, R⁸, and R⁹ are independently an unsubstituted or substituted C_1-20 hydrocarbon group; and R⁶ is hydrogen atom or methyl group. This compound is hydrolyzed at a reduced speed, and use of a polymer obtained by copolymerization with an alkyl methacrylate is capable of suppressing attachment of marine organisms to the ship with no or reduced biocide, and this polymer is useful for a hydrolytic self-polishing paint.
