Zusammenfassung:Novel compounds of formula I [wherein X is a direct bond, sulfur or -CHR5-, R1 is hydrogen, C1-C25alkyl, unsubstituted or C1-C4alkyl-substituted C5-C8cycloalkyl; unsubstituted or C1-C4alkyl-substituted C5-C8cycloalkenyl; unsubstituted or C1-C4alkyl-substituted phenyl; C7-C9phenylalkyl or -CH2-S-R6; R2 is hydrogen, C1-C25alkyl, C2-C24alkenyl, unsubstituted or C1-C4alkyl-substituted C5-C8cycloalkyl; unsubstituted or C1-C4alkyl-substituted C5-C8cycloalkenyl; unsubstituted or C1-C4alkyl-substituted phenyl; C7-C9phenylalkyl or -CH2-S-R6; R3 is hydrogen or methyl; R4 is C1-C8alkyl, O DEG , OH, NO, -CH2CN, C1-C18alkoxy, C5-C12cycloalkoxy, C3-C6alkenyl, C3-C6alkynyl, C1-C8acyl, C7-C9phenylalkyl which is unsubstituted or substituted at the phenyl ring by C1-C4alkyl; R5 is hydrogen or C1-C8alkyl; and R6 is C1-20alkyl] are stabilisers for protecting organic materials against oxidative, thermal or light-induced degradation. They are particularly suitable as processing stabilisers for synthetic polymers.
