Abstract

The present invention provides carboxylic acid amides of the formula ##STR1## in which X represents methyl or tertiary butyl, m is the integer 1 or 2, Q represents hydrogen, alkyl, alkylidene, cycloalkylidene, substituted methylene, alkylene, alkenylene or a 3,4,5 or 6-valent saturated aliphatic hydrocarbon radical and p represents an integer which corresponds to the valency of the radical Q. These carboxylic acid amides are suitable for stabilizing organic materials sensitive to oxidations.
