Abstract

[Object] To provide a polymerizable silicone monomer that yields a polymer having excellent transparency, surface hydrophilicity, durability, and stain resistance, and a method for preparing the polymerizable silicone monomer. Another object of the present invention is to provide a curable composition containing the polymerizable silicone monomer, a polymer obtained by polymerizing the composition, and an ophthalmic device comprising the polymer.[Solution] A polymerizable silicone monomer represented by the following formula (1):wherein R¹ is, independently of each other, a monovalent hydrocarbon group having 1 to 4 carbon atoms, R² is, independently of each other, an alkyl group having 1 to 10 carbon atoms or an aryl group having 6 to 10 carbon atoms, R³ is a hydrogen atom or a methyl group, A¹ is a single bond or a divalent hydrocarbon group having 1 to 20 carbon atoms, Q is a divalent group selected from the group consisting of -A²-O-A³-and -O-A⁴-O-, A² and A³ are, independently of each other, a single bond or an optionally branched divalent hydrocarbon group having 1 to 3 carbon atoms wherein at least one hydrogen atom bonded to a carbon atom of the divalent hydrocarbon group may be substituted with an alkoxy group having 1 to 4 carbon atoms, provided that A² and A³ are not both single bonds, A⁴ is an optionally branched divalent hydrocarbon group having 1 to 3 carbon atoms wherein at least one hydrogen atom bonded to a carbon atom of the divalent hydrocarbon group may be substituted with an alkoxy group having 1 to 4 carbon atoms, and n is an integer of 1 to 3.
