ABSTRACT:
This invention relates to the improvement of rubber-to-metal adhesion and adhesion retention in sulfur vulcanizable, metal reinforced rubber compositions via the use of substituted pyrimidine and triazine adhesion promoters of Structure (I). ##STR1## wherein A is N or C-H, X, Y and Z are independently selected from the group consisting of chloro, ##STR2## wherein R.sub.1 may be hydrogen, chloro, acyl, or C.sub.1 -C.sub.12 alkyl; R.sub.2 may be hydrogen, C.sub.1 -C.sub.12 alkyl, chloro, hydroxy, alkoxy, or anilino; R.sub.3 may be hydrogen, C.sub.1 -C.sub.4 alkyl or phenyl; R.sub.4 may be hydrogen, C.sub.1 -C.sub.8 alkyl, cyclohexyl, C.sub.1 -C.sub.12 hydroxylalkyl, or C.sub.1 -C.sub.12 alkoxyalkyl; R.sub.5 may be hydrogen, C.sub.1 -C.sub.4 alkyl, cyclohexyl, or C.sub.1 -C.sub.12 hydroxyalkyl; with the proviso that Z may not be chloro when both X and Y are chloro.
