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 ##STR1## e.g., 4-anilino-2,2,2-trichloroacetanilide protects NBR even after sequential exposure to oil and to air at elevated temperature.
弹性体和塑料聚合物可以通过某些新的取代卤代醋酰胺抗氧化剂来保护不受恶化,这些抗氧化剂是非迁移性的,并且抗油和溶剂的提取,例如4-苯胺基-2,2,2-三氯乙酰胺保护NBR,即使在升高温度下顺序接触油和空气后。
