摘要 |
<p>A phenol compound of the formula Ä1Ü <CHEM> wherein each of X's is a group of the formula Ä2Ü <CHEM> wherein R1 and R4 are the same or different and each is an alkyl having 1 to 8 carbon atoms, and R2, R3, R5 and R6 are the same or different and each is a hydrogen atom or an alkyl having 1 to 8 carbon atoms; a stabilizer for organic materials which comprises the compound; a composition comprising the compound and an organic material; and a composition comprising the composition and a sulfur antioxidant, and use thereof. The compound of the present invention as used as a stabilizer for an organic material shows superior preventive effect against oxidative degradation and extremely superior resistance against degradation of an organic material in an environment involving contact with hot water for a long time, as compared to compounds conventionally used as hot water resistant antioxidants. In addition, a concurrent use of the compound of the present invention and a sulfur antioxidant brings about excellent synergistic effect to synergistically improve resistance to hot water for a long time, as compared to conventional hot water resistant antioxidants.</p> |
