    Patent number: 5120779
    Abstract: A new class of antiozonant compounds, namely tris(N-alkyl-p-phenylenediamino)-1,3,5-triazine compounds, are incorporated into thermosetting compositions having at least one highly unsaturated rubbery polymer and at least one other elastomer having lesser unsaturation, such as EPDM. Thermosetting compositions are most useful as tire sidewall compositions which may be preferably cured with blends of organic peroxide and sulfur donor accelerators.
    Type: Grant
