Abstract

NEW MATERIAL:An N,N'-asymmetrically substituted paraphenylenediamine of formula I (R0, R1 and R2 are H or lower alkyl; R3 is lower alkyl; R4 is alkyl or cycloalkyl).
EXAMPLE: N-(α-Methylbenzyl)-N'-(1,3-dimethylbutyl)-p-phenylenediamine.
USE: Agent for improving ozone aging resistance, heat aging resistance, and flex-crack resistance of a rubber polymer.
PROCESS: The compound of formula I is prepared by reacting an N-(substituted arylmethyl)-p-phenylenediamine of formula II with an aliphatic or cycloaliphatic ketone or aldehyde, and hydrogen.
