摘要：
The present invention relates to the combined use of sulfite and/or at least one thiosulfate and a polymeric or oligomeric hindered amine for stabilizing organic materials, in particular against oxidative thermal and/or actinic degradation. The present invention further relates to correspondingly produced compositions, to moldings producible from these compositions, to a method for stabilizing organic materials and to possible uses of the stabilized organic materials.
