| titleOfInvention | Raw materials for silicone monomers and ophthalmic lenses |
| abstract | A silicone compound that can be suitably used as a monomer that provides a polymer suitable for an ophthalmic lens such as a contact lens is provided with high purity. The dihydroxyalkyl is a hydrolyzate of (a) and / or (a ′), wherein the purity of the silicone compound represented by the following general formula (a) and / or (a ′) is 87% or more. The silicone compound whose content rate of the silicone compound which has group is 0.4% or more and 3% or less. (Here, A represents a siloxanyl group. R 1 represents a substituent having 1 to 20 carbon atoms having a polymerizable group. R 2 to R 4 are each independently hydrogen and optionally substituted 1 carbon atom. Represents a substituent of -20 or -X-A. X represents an optionally substituted divalent substituent having 1 to 20 carbon atoms.) [Selection figure] None |
