Abstract
Methods for incorporating hydrophilic constituents into silicone polymer materials are disclosed. In one embodiment, the method comprises introducing a hydrophilic component into a cross-linked and/or solid silicone polymeric material, and subjecting the hydrophilic component to conditions effective to immobilize the hydrophilic component or a hydrophilic derivative thereof and form a silicone polymer material including an effective hydrophilic constituent.
