Summary: | Stabilized polyamides containing from 0.02 to 5%, by weight of a diphenylamine compound corresponding to the following general formula: (I) wherein R1 and R3, which may be the same or different, represent hydrogen, a CH3-, C2H5- or isopropyl group and R3 is in the o-, m- or p-position to the N-atom substitution; R2 represents hydrogen, a C4-C12 alkyl, C7-C12 aralkyl or C5-C12 cycloalkyl group and is in the o-, or p-position to the N-atom substitution; n represents an integer of from 1 to 29; and Y is a divalent, non-mono-olefinically unsaturated radical having the same meaning as R2 and, in addition, may represent (in a proportion of up to 50 mole percent) -S-, -CH2-S-CH2+13, -CH2-O-CH- or >CH-R4, wherein R4 represents H, C1-C6 alkyl or C5 or C6 cycloalkyl, and may be in the o- or p-position to the N-atom substitution. |
