Abstract
Process for the stabilization of synthetic materials, characterized in that diamides of oxalic acid of the formula are fused with the synthetic materials ** (see formula) ** In which R means a dialkylamino group whose alkyl radicals each contain 1 to 6 carbon atoms, A di- (hydroxyalkyl) -amino group whose hydroxyalkyl radicals each contain 2 to 4 carbon atoms; O well A monocyclic saturated hetcrocyclic radical, which is linked (by a nitrogen atom bonded exclusively to carbon) with the group -cnh2n- which contains, like other members of the ring, 4 to 5 carbon atoms and as many oxygen atoms or other atoms of nitrogen, that the number of the members of the ring is 5 or 6; y N means an integer value of 2 at least.
