The invention relates to compositions based on polyoxymethylene, polycarbonate mixtures with an acrylonitrile-butadiene-styrene terpolymer, or an acrylic resin system functional with a crosslinking agent, which are stabilized by the addition of a compound containing residues of 3,3,5,5-tetraalkylpiperazine-2,6-dione. The invention also relates to novel compounds of this class, the use of the new compounds as stabilizers for protecting an organic material, such as a thermoplastic organic polymer, a coating binder or a photographic material, against degradation by light, oxygen and / or heat, and thus stabilized organic matter.Application area: Stabilizers for organic materials. |
