ABSTRACT:
The present invention relates to synergistic mixtures for stabilising polymeric organic materials against light, heat and oxidation; said synergistic mixtures contain sterically hindered cyclic amines and particular derivatives of 3-pyrazolidinone or 1,2,4-triazolidine-3,5-dione. In addition, the present invention relates to some new derivatives of 3-pyrazolidinone or 1,2,4-triazolidine-3,5-dione.
