Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of making an oxidation-resistant cross-linked polymeric material comprising the steps of: a) blending a polymeric material with an antioxidant, wherein a first portion of the polymeric material is contacted with a concentration of an antioxidant, a second portion of the polymeric material is contacted with another concentration of the antioxidant, and a third portion of the polymeric material is contacted with another concentration of the antioxidan…
