Abstract: Disclosed are tris-substituted 1,3,5-triazine compounds having at least one (N-alkyl-p-phenylendediamino) group on the triazine ring. The preferred compositions are tri-substituted with the alkyl p-phenylenediamino group. The preferred compounds may be prepared by reacting N-alkylphenylenediamine with a cyanuric halide.

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.

Abstract: Novel N-alkyl-p-quinonedimino trizazine compounds are disclosed which are useful as antiozonants for unsaturated high polymers. The compound may be prepared by oxidizing a 2,4,6-tris-(N-alkyl-p-phenylenediamino) 1,3,5-triazine with a neutral or basic oxidizing agent and isolating the product.

Abstract: Disclosed are novel 2,4,6 substituted pyrimidines where the substituents may be the same or different groups.
