The present invention discloses a process for incorporating an elastomeric composition and a hydrocarbon polymer modifier with improved persistence. The composition comprises an elastomer, a filler and a silane-functionalized hydrocarbon polymer modifier (Si-HPM), wherein Si-HPM is adapted to couple Si-HPM to an elastomer, filler, or both, and Si- HPM includes copolymers of monomers selected from piperylene, cyclic pentadiene, aromatics, limonene, pinene, amylene and combinations thereof. The method comprises melt processing the mixture to form the elastomer composition into an article shape, wherein the mixture comprises an elastomer, Si-HPM, silica, a bifunctional organosilane crosslinker, and curing the elastomer composition to Forming a step. The present invention also discloses a silylated hydrocarbon polymer modifier coupled with a bifunctional organosilane crosslinker, and a silicaca-coupled hydrocarbon polymer modifier coupled to silica via a bifunctional organosilane crosslinker. have. |
