Abstract
Novel, nonabsorbable antioxidants of the general formula (An).sub.n R wherein An is a means for preventing oxidation of an oxidizable material, R is a means for essentially restricting the absorption of An in a biological environment, .about. is a means for covalently bonding An to R for a prolonged time, and n is at least one. The nonabsorbable antioxidants are useful as stabilizers in oxidizable materials without any substantial absorption of the antioxidant in the biological environment.
