    摘要: The instant invention discloses a process for preventing contact discoloration of substrates coming into contact with elastomers and stabilizing elastomers to prevent oxidative, thermal, dynamic, light-induced and/or ozone-induced degradation, which comprises incorporating into the elastomers, or applying to these, at least a compound of the formula (I) wherein R1 is C1-C12alkyl, R2 is C1-C12alkyl, or R1 and R2 together with the carbon atom to which they are attached form an unsubstituted or with C1-C4alkyl substituted C5-C12cycloalkyl ring; R3 is hydrogen or —CH2—S(O)m—R5, R4 and R5 independently of each other are unsubstituted or with cyano substituted C5-C18-alkyl; C7-C9phenylalkyl, unsubstituted or with halogen, hydroxyl, cyano or C1-C4alkyl substituted phenyl or naphthyl; benzothiazolyl or —R6—CO2—R7, R6 is C1-C18alkylene, R7 is C1-C18alkyl, and m is 0, 1 or 2. The instant invention discloses also novel compounds of the formula (I), new mixtures of compounds of the formula (I) and compositions thereof in elastomers.
