STABILIZER MIXTURE

摘要

A mixture comprising A. at least one oligomeric compound comprising repeat units of the formula (I) in which the symbols are each defined as follows: R¹ is hydrogen, C₁- to C₆-alkyl, formyl, C₂- to C₆-alkanoyl, C₁- to C₁₂-alkoxy, C₅- to C₆-cycloalkoxy, cyanomethyl, 2-hydroxyethyl, benzyl or a radical of the formula -CR'=CH-CO-OR' where R' is hydrogen, C₁- to C₆-alkyl or a radical of the formula -CO-OR', and R' is C₁- to C₁₈-alkyl, C₅- to C₈-cycloalkyl, C₇- to C₁₈-aralkyl, phenyl or tolyl; R² is a mixture of C₁₄- to C₂₈-alkyl groups, where two of these alkyl groups, which must not differ by more than two carbon atoms, each make up at least 30% of this mixture; R³, R⁴ are each independently C₁- to C₆-alkyl; and B. at least one compound of the formula (II) or (III) where the symbols and indices are each defined as follows: n, m are each independently a natural number from 2 to 22 and R¹, R³, R⁴ are each independently defined as specified in formula (I); is suitable as stabilizers for organic material.
