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; Ris hydrogen or an alkyl containing 1-20 carbon atoms, which can be substituted with a hydroxyl; Ris a C-alkylene group, which can be substituted with a hydroxyl; R-Rindependently denote C-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.18 cl, 1 dwg, 2 tbl, 21 ex |
