Abstract
The present invention relates to the use of efficient phosphorous substances, in particular based on diphenylamine and heterocyclic diphenylamine derivatives as stabilizers for organic materials, in particular for plastic materials, against oxidative, thermal and/or actinic degradation. The present invention additionally relates to an organic material that has been correspondingly stabilized as described above. The invention further relates to a method of stabilizing organic materials and to specific stabilizers.
