Elastomers and plastic polymers are protected against deterioration by certain new substituted haloacetamide antioxidants which are non-migratory and resist extraction by oils and solvents, of the type <IMAGE> or <IMAGE> e.g., 4-anilino-2,2,2-trichloroacetanilide protects NBR even after sequential exposure to oil and to air at elevated temperature. |
