Disclosed is a compound represented by formula (I) [wherein Ra and Rb independently represent an organic group which has 1 to 30 carbon atoms and may have a substituent; X1 and X2 independently represent a hydrogen atom, a halogen atom, an alkyl group which has 1 to 10 carbon atoms and may have a substituent, a cyano group, a nitro group, -OR, -O-C(=O)-R, -C(=O)-OR, -O-C(=O)-OR, -NRR0, -NR-C(=O)-R0, -C(=O)-NRR0, or -O-C(=O)-NRR0 (wherein R and R0 independently represent a hydrogen atom or an organic group which has 1 to 20 carbon atoms and may have a substituent, and multiple X1 and X2 may be substituents that are different from each other); and n and m independently represent an integer of 0 to 2 (wherein it is inconceivable that both n and m represent 0)]. Also disclosed is an anti-aging agent, particularly an anti-aging agent for polymers, which comprises the compound. Further disclosed is a polymer composition, particularly a rubber composition, which contains the compound. |
