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, optionally, other elastomers having lesser unsaturation, such as EPDM and butyl rubber. Thermosetting compositions are most useful as tires, belts, hose, sheeting and other rubber articles. The compositions which may be preferably cured with blends of organic peroxide and sulfur donor accelerators. |
