PHENOL 2-(A-C(-R1)(-R2)-),(R4-O-P(=S)(-O-R5)-S-CH2-)N,(R3)(2-N)- WHEREIN A, R1 AND R2 ARE THE SAME AS ABOVE; R4 AND R5 ARE INDEPENDENTLY SELECTED FROM THE GROUP CONSISTING OF ALKYL RADICALS CONTAINING FROM 1-50 CARBON ATOMS AND ARYL RADICALS CONTAINING FROM 6-20 CARBON ATOMS, AND N IS 1 OR 2. AN EXAMPLE IS S-!3,5-DI-(A-METHYLBENYL)-4-HYDROXYBENZYL!!-0,0-DI-(20-50 PRIMARY ALKYL) PHOSPHORODICITHIOATE. A PROCESS OF MAKING THE COMPOUNDS BY THE REACTION OF 3,5-DIHYDROCARBYL-4HYDROXYBENZYL HALIDE WITH AN 0,0-DI-HYDROCARBYL DITHIOPHOSPHORIC ACID IN THE PRESENCE OF AN ALKALI METAL BASE OR AN ALKALINE EARTH METAL BASE IS ALSO DISCLOSED. A-C(-R1)(-R2)- WHEREIN AN ARYL RADICAL CONTAINING FROM 6-18 CARBON ATOMS, R1 IS ALOWER ALKYL RADICAL CONTAINING FRON 1-3 CARBON ATOMS, R2 IS SELECTED FROM HYDROGEN AND LOWER ALKYL RADICALS CONTAINING FROM 1-3 CARBON ATOMS, R3 IS SELECTED FROM THE GROUP CONSISTING OF ALKYL RADICALS CONTAINING FROM 1-20 CARBON ATOMS, CYCLOALKYL RADICALS CONTAINING FROM 6-20 CARBON ATOMS AND RADICALS HAVING THE FORMULA: STYRENE-BUTADIENE RUBBER IS STABLIZED BY ADDITION OF A COMPOUND HAVING THE FORMULA |
