PROBLEM TO BE SOLVED: To improve the permanence of rubber compounding additives in general and improve wet traction in a tire tread while maintaining or improving treadwear and rolling resistance.SOLUTION: There are provided an elastomer composition and a method that incorporate a hydrocarbon polymer modifier with improved permanence. The composition comprises an elastomer, a filler and a silane-functionalized hydrocarbon polymer modifier (Si-HPM). The Si-HPM is configured to couple to the elastomer, the filler or both, and comprises an interpolymer of monomers selected from piperylene, cyclic pentadiene, aromatic, limonene, pinene, amylene, and combination thereof. The method comprises melt processing a mixture to form the composition into the shape of an article, where the mixture comprises the elastomer, the Si-HPM, silica, a bifunctional organosilane crosslinking agent; and curing the elastomer composition to form the article. Also disclosed are a silylated hydrocarbon polymer modifier coupled with a bifunctional organosilane crosslinking agent, and a silica-coupled hydrocarbon polymer modifier coupled to the silica via the bifunctional organosilane crosslinking agent. |
