    摘要: Substituted hydroxylamine ester stabilizers corresponding to the for­mula I
    wherein n is an integer from 0 to 2, X is a direct bond, -S- or -CH₂S-, R₁ and R₂ independently are hydrogen, alkyl of 1 to 36 carbon atoms, cycloalkyl of 5 to 12 carbon atoms, allyl, aryl, aralkyl of 7 to 9 carbon atoms, said aralkyl substituted by alkyl of 1 to 36 carbon atoms, or R₁ and R₂ together with the nitrogen atom to which they are linked form a 5 - 7 membered heterocyclic ring, R₃ and R₄ independently are alkyl of 1 to 18 carbon atoms, cycloalkyl of 5 to 6 carbon atoms, phenyl, alkaryl of 7 to 18 carbon atoms or aralkyl of 7 to 9 carbon atoms, and R₅ is hydrogen or the group
    are effective in stabilizing organic materials against oxidative, thermal and actinic degradation.
