Abstract
The present invention relates to methods for making cross-linked oxidation-resistant polymeric materials and preventing or minimizing in vivo elution of antioxidant from the antioxidant-containing polymeric materials. The invention also provides methods of doping polymeric materials with a spatial control of cross-linking and antioxidant distribution, for example, vitamin E (α-Tocopherol), and methods for extraction/elution of antioxidants, for example, vitamin E (α-tocopherol), from surface regions of antioxidant-containing polymeric materials, and materials used therewith also are provided.
