This invention relates to organic materials normally susceptible to gradual degradation in the presence of oxygen during use over an extended period of time and of the type in which it is customary to add an antioxidant thereto to prevent degradation. The improvement constituting the basis of this invention comprises including an alkenylated toluenediamine having one alkenyl group ortho to an amine group. More particularly, the alkenylated toluenediamines suited as antioxidants are represented by the formulas: ##STR1## wherein R.sub.1, R.sub.2, R.sub.3, R.sub.4 and R.sub.5 are hydrogen, C.sub.1 to C.sub.3 aliphatic, or R.sub.1 and R.sub.2 or R.sub.3 are bridged via an alkylene radical --(CH.sub.2).sub.y -- wherein y=2 to 5, and at least one of R.sub.1, R.sub.2, R.sub.3, R.sub.4 or R.sub.5 is C.sub.1 or greater.
