Notes:
Aldonitrones are effective melt stabilizers for polypropylene, the most effective being benzaldonitrones containing a partially hindered 4-hydroxy group in the aromatic ring. They form nitroxyl radicals in the polymer during processing, and these and the related hydroxylamines are believed to be involved in a catalytic CB—A/CB—D antioxidant cycle during mechano- and photooxidation. During thermal oxidation (oven aging) they behave as stoichiometric CB-D antioxidants.
