摘要:
The present invention relates to a polymers and hydrogels comprising a sulfonic acid component formed from reactive components comprising (i) at least one hydrophobic monomer and (ii) at least one sulfonic acid-containing component, wherein the sulfonic acid-containing component is comprised of a salt formed by a non-polymerizable, hydrophilic base and a polymerizable sulfonic acid. One or more embodiments provide that the at least one hydrophobic monomer comprises a silicone component.
摘要:
The present invention relates to a silicone acrylamide copolymer of high acrylamide monomer content which has transparency and low modulus, employing the following configuration. The copolymer is suitably used for various kinds of medical devices, particularly ophthalmic lenses such as a contact lens, an intraocular lens, an artificial cornea, and is especially suitable for a contact lens.A copolymer comprising (A) a multi-functional (meth)acrylamide monomer having at least one siloxane bond and at least two (meth)acrylamide groups within a molecule and (B) a mono-functional linear silicone (meth)acrylamide monomer.
