    摘要: The invention relates to a compound of the formula (I) in which: - R1 represents, independently of each other, a halogen atom; an aliphatic hydrocarbon-based group optionally substituted and/or optionally interrupted by one or more oxygen or sulfur atoms; a nitro group; a cyano group; an amino group; a mono- or dialkylamino group; an alkylcarbonyl group; a carboxyl group; an alkylcarbonylamino group; an alkylsulfonyl group; - R2 represents, independently of each other, a cyano group; a hydroxyl group, an alkylcarbonyl group; a carboxyl group; an alkoxycarbonyl group; an unsubstituted amide group; or a linear or branched alkyl group substituted by a cyano, hydroxyl, carboxyl, alkoxycarbonyl or unsubstituted amide group; - i and j independently being 1 to 5, with the exclusion of the compound for which i and j = 1 and R1 = carboxyl and R2 = alkoxycarbonyl or R1 = CF3 and R2 = carboxyl, and also the pharmaceutically acceptable derivatives, salts, solvates and stereoisomers thereof, including mixtures thereof in all proportions.

    摘要: Compounds of the formula (I) wherein R1 is C1-C18alkyl, C5-C12-cycloalkyl, phenyl, benzyl, or allyl; n is 1 or 2; if n is 1, R2 is C4-C18alkyl, C5-C12­cycloalkyl, aryl or heteroaryl, benzyl, allyl, (CH2),mCOOR3, or is (CH2)mCN; if n is 2, R2 is -S-(CH2)p-S or -S-(CH2)2-[O-(CH2)2]m-S­ R3 is C1-C18alkyl, benzyl, allyl; m is 1 or 2; and p is a number from 2 to 12; are suitable as a stabiliser for an elastomer to prevent oxidative, thermal, dynamic, light-induced and/or ozone­induced degradation. They are also suitable as stabilizers for elastomers to prevent contact discoloration of substrates coming into contact with elastomers.
