Abstract
The present invention relates to a silicone polymer comprising a sulfonic acid component formed from reactive components comprising (i) at least one silicone component and (ii) at least one sulfonic acid-containing component, wherein the sulfonic acid-containing component is comprised of a non-polymerizable, hydrophobic cation and a polymerizable sulfonic acid.
Claims19
A process for forming a silicone polymer comprising a sulfonic acid component comprising (a) polymerizing reactive components comprising (i) at least one silicone component and (ii) at least one sulfonic acid-containing component, wherein said sulfonic acid-containing component is comprised of a non-polymerizable, hydrophobic cation and a polymerizable sulfonic acid;
- and (b) removing the non-polymerizable, hydrophobic cation from said silicone polymer.
