SILICONE (METH)ACRYLAMIDE MONOMER, POLYMER, OPHTHALMIC LENS AND CONTACT LENS Russian patent published in 2015 - IPC C07F7/08 C08G77/20 G02B1/04 G02C7/04 

FIELD: chemistry.

SUBSTANCE: invention relates to a silicone (meth)acrylamide monomer, the molecules of which contain a straight chain siloxanyl group and preferably a hydroxyl group. Disclosed is a silicone (meth)acrylamide monomer of general formula (a), where R is hydrogen or methyl; R¹ is hydrogen or an alkyl containing 1-20 carbon atoms, which can be substituted with a hydroxyl; R² is a C_1-10-alkylene group, which can be substituted with a hydroxyl; R³-R⁹ independently denote C_1-20-alkyl, which can be substituted with a hydroxyl, n is an integer from 1 to 10. A polymer obtained from said monomer is also disclosed, as well as an ophthalmic lens and a contact lens made therefrom.

EFFECT: obtaining lenses with high oxygen permeability and flexibility
