Abstract
Stabilizing compositions for organic polymers, composed of mixtures of at least one liquid phenolic antioxidant and at least one aminic antioxidant, subjected to thermal treatment, are characterized by their stabilizing capacity which is considerably higher than that of either single components or of corresponding untreated mixtures. These stabilizing compositions can be used in all field where the single components of the mixtures are generally used and, preferably, in the stabilization of organic polymers normally subject to deterioration due to oxidation processes.
