ABSTRACT:
Methods for incorporating beneficial components into polymeric materials are disclosed. In one embodiment, the method comprises introducing a reactable UV light absorbing component into a cross-linked and/or solid polymeric material containing reactable groups, and subjecting the reactable UV light absorbing component to conditions effective to chemically react the reactable UV light absorbing component with the reactable groups of the solid polymeric material.
