Ozone resistant O2/N2 gas separation membranes comprise a polymer membrane and an ozone reacting component, such as an antioxidant. The antioxidant may be included in the support layer of a composite membrane or included in the entire structure of an asymmetric membrane. The antioxidants in the separation membrane reduce oxidation and deterioration of the actual separation layer of the membrane.

We claim: 1. An apparatus comprising: a gas separation membrane; and an ozone reacting component incorporated in said gas separation membrane. 2. The apparatus of claim 1, wherein said gas separation membrane comprises a composite membrane having a support layer and a separating layer, said ozone reacting component incorporated in said support layer. 3. The apparatus of claim 1, wherein said gas separation membrane comprises an asymmetric membrane having a porous region and a separating region, said ozone reacting component incorporated in said porous region and said separating region. 4. The apparatus of claim 1, wherein said gas separation membrane comprises at least one of polysulfone, polyether, polyamide, polycarbonate, polyethersulfone, polysilicone, polyimide, polyetherimide, polyestercarbonate, and mixtures and copolymers thereof. 5. The apparatus of claim 1, wherein said ozone reacting component comprises an antioxidant. 6. The apparatus of claim 1, wherein said ozone reacting component comprises at least one of olefin and polyolefin. 7. The apparatus of claim 1, wherein said ozone reacting component comprises less than about 10% by weight of said apparatus. 8. The apparatus of claim 1, wherein said apparatus comprises a hollow tube membrane. 9. The apparatus of claim 1, wherein said ozone reacting component comprises between about 1% and about 5% by weight of said apparatus. 10. The apparatus of claim 1, wherein said ozone reacting component comprises at least one of phosphite esters, organic sulfides, retinol, isoprenoid hydrocarbons, polybutadienes, polyisoprenes and aromatic amines. 11. An asymmetric membrane comprising: a porous region; a separating region integral to said porous region; and an ozone reacting component incorporated in said porous region and said separating region. 12. The asymmetric membrane of claim 11, wherein an oxygen/nitrogen separation factor of said asymmetric membrane is at least about 2. 13. The asymmetric membrane of claim 11, wherein said ozone reacting component comprises less than about 5% by weight of said asymmetric membrane. 14. The asymmetric membrane of claim 11, wherein said ozone reacting component comprises an antioxidant that acts as a sacrificial reductant. 15. The apparatus of claim 11, wherein said ozone reacting component comprises at least one of olefin and polyolefin. 16. A composite membrane comprising: a support layer; a separating layer in contact with said support layer; and an ozone reacting component incorporated in said support layer. 17. The composite membrane of claim 16, wherein said composite membrane comprises polyetherimide. 18. The composite membrane of claim 16, said ozone reacting component includes at least one of phosphite esters, organic sulfides, retinol, aromatic amines, isoprenoid hydrocarbons, polybutadienes, polyisoprenes, olefin, and polyolefin. 19. The composite membrane of claim 16, wherein said composite membrane comprises a flat sheet. 20. The composite membrane of claim 16, wherein said ozone reacting component comprises less than about 10% by weight of said composite membrane.
