Abstract: ANTI-OXIDANTS ARE DISCLOSED HAVING THE FORMULA:

R-O-P(-O-R'')(=S)-S-M-S-P(=S)(-O-R")-O-R"''

WHEREIN M IS CALCIUM, BARIUM, NICKEL, CADMIUM, LEAD OR ZINC AND R, R'', R" AND R"'' ARE SUBSTITUTED OR UNSUBSTITUTED HYDROCARBON RADICALS, AT LEAST ONE HAVING THE FORMULA:

(2-R2,3-R1,4-R3,5-R4,5-R5-PHENYL)-(A)N-

WHEREIN A IS A BIVALENT HYDROCARBON RADICAL AND N IS ZERO OR A WHOLE NUMBER FROM 1 TO 20 AND AT LEAST ONE OF SAID R1, R2, R3, R4 AND R5 GROUPS IS A HYDROXY GROUP STERICALLY HINDERED BY ANOTHER OF SAID GROUPS WHICH IS AN ALKYL GROUP. THE REMAINING GROUPS ARE HYDROGEN OR ALKYL.
