Abstract:
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.
