Abstract
Novel N-alkyl-p-quinonediimino triazine 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.
Claims2
A degradation-resistant composition comprising:
- an unsaturated polymer having homogeneously incorporated therein an effective amount of one or more compounds of the general formula:
- ##STR3## Y and Z are independently selected from ##STR4## in which R.sup.1, R.sup.2 and R.sup.3 are radicals independently selected from a C.sub.3 -C.sub.18 branched or linear alkyl, or a C.sub.3 -C.sub.12 cycloalkyl or a C.sub.3 -C.sub.12 cycloalkyl substituted with one or more C.sub.1 -C.sub.12 alkyl groups.
A tire having an elastomeric body including carcass, tread and sidewall portions, said elastomeric body comprising:
- a plurality of thermosetting rubber polymers therein;
- and a plurality of reinforcing materials positioned within said body, at least one of said plurality of thermosetting rubber polymers having dispersed therein an antidegradant composition composed of one or more compounds of the general formula:
- ##STR5## Y and Z are independently selected from ##STR6## in which R.sup.1, R.sup.2 and R.sup.3 are radicals independently selected from a C.sub.3 -C.sub.18 branched or linear alkyl, or a C.sub.3 -C.sub.12 cycloalkyl or a C.sub.3 -C.sub.12 cycloalkyl substituted with one or more C.sub.1 -C.sub.12 alkyl groups.
