Abstract
Process for increasing the aging stability of polymeric materials, characterized in that 4-benzoylresorcinol derivatives of the general formula are added to the mentioned materials: ** (See formula) ** to which effect they mean: R1 is a hydroxyl group or an alkoxy group, of not more than two carbon atoms. R2 a hydroxyl group or an alkoxy group, at most two carbon atoms. R3 hydrogen or a hydroxyl group. R4 hydrogen or a group, hydroxyl. (Machine-translation by Google Translate, not legally binding)
