FIELD: chemistry.
SUBSTANCE: invention relates to polymers for producing ionic silicone hydrogels suitable for making ophthalmic devices. Disclosed are polymers obtained from reactive components comprising at least one silicone-containing component which includes at least one trimethylsilyl group and at least one ionic component comprising at least one anionic group, which is a carboxylic acid-containing component. Also disclosed is a contact lens made from the disclosed polymers.
EFFECT: disclosed polymers demonstrate improved thermal stability and desirable protein uptake.
