  • Patent number: 9062189
    Abstract: Provided are elastomeric compositions comprising at least one elastomer and a hydrocarbon polymer additive. Preferably the hydrocarbon polymer additive comprises from 60 to 90% piperylene, from 5 to 15% cyclic components, from 5 to 20% styrenic components, up to 5% isoprene, up to 5% indenic components, and up to 10% amylene. Also provided are elastomeric compositions comprising at least one elastomer and a hydrocarbon polymer additive, wherein the hydrocarbon polymer additive has a molecular weight of from 520 to 650 g/mole and a glass transition temperature (Tg) of from 48 to 53° C. The elastomeric compositions are particularly useful in making tires and other cured rubber articles.
