(57) [Summary]nA) All substituents in the α-position to the nitrogen atom of the amine are selected from secondary amines different from hydrogen, or tertiary amines derived from secondary amines, hydroxylamines, alkoxylamines or amides A stabilizer composition is described, comprising at least one nitrogen compound having a molecular weight of at least 150, and B) at least one iron compound. The stabilizer composition optionally contains a nitroxyl radical. The compositions are suitable for stabilizing non-viable organic materials, especially polyolefins or styrene homopolymers or copolymers, against the action of light, heat or oxygen. |
