SILICONE HYDROGELS CONTAINING HIGH POLYAMIDE LEVELS Russian patent published in 2021 - IPC C08F290/06 C08L83/10 C08J3/75 C08L51/08 G02B1/04 G02C7/04 

Abstract RU 2757907 C2

FIELD: biochemistry.

SUBSTANCE: invention relates to silicone hydrogels having increased biocompatibility. Silicone hydrogel is proposed formed of a reaction monomer mixture containing: hydroxyalkyl(meth)acrylate monomer; silicone components containing a hydroxyl group; and polyamide, wherein polyamide is present in the amount of more than 15% by wt. per the total weight of reactive components in the reaction monomer mixture. A method for producing silicone hydrogel and contact lenses containing the proposed silicone hydrogel are also proposed.

EFFECT: proposed silicone hydrogels with high polyamide levels show excellent balance of physical, mechanical and biological properties.
