Claims
- 1. Organic material normally susceptible to gradual oxidative degradation, containing an antioxidant amount of an adduct formed by reacting at least about 0.05 mole parts of a phosphorus trihalide of formula PX.sub.3 where the X are halides with one mole part of a large phenolic compound having four or more phenolic moieties, said phenolic compound being a calix (n) arene where n=4 to 10.
- 2. The composition of claim 1 wherein n=6.
- 3. The composition of claim 1 wherein the calix (n) arene is formed from p-tert-butylphenol.
- 4. The adduct formed by reacting at least about 0.05 mole parts of a phosphorus trihalide of formula PX.sub.3 where the X are halides with one mole part of a calix (n) arene where n=4 to 10.
- 5. The adduct of claim 4 wherein n=4.
- 6. The adduct of claim 4 wherein n=6.
