ABSTRACT:
Elastomeric compositions produced by curing blends comprising (A) a highly unsaturated rubber; (B) a saturated rubber; (C) a phenylenediamine compound and (D) a curing agent comprised of (i) sulfur and/or a sulfur donor compound, (ii) a sulfur cure accelerator, and (iii) a peroxide curative; wherein between about 1 and about 10 parts by weight of (C) per 100 parts by weight of (A) plus (B) is present exhibit unexpectedly high resistance to cut growth. In addition, a process for producing such rubber compositions is disclosed.
