An elastomeric composition and method incorporating a hydrocarbon polymer modifier with improved permanence. The composition comprises elastomer, filler and silane-functionalized hydrocarbon polymer modifier (Si-HPM) adapted to couple the Si-HPM to the elastomer, filler or both, wherein the Si-HPM comprises an interpolymer of monomers chosen from piperylenes, cyclic pentadienes, aromatics, limonenes, pinenes, amylenes, and combinations thereof. The method comprises melt processing the mixture to form an elastomeric composition in the shape of the article, wherein the mixture comprises an elastomer, Si-HPM, silica, a difunctional organosilane crosslinker; and the elastomeric composition is cured to provide an article. Also disclosed is a silylated hydrocarbon polymer modifier coupled to a bifunctional organosilane crosslinker, and a silica-coupled hydrocarbon polymer coupled to the silica via a bifunctional organosilane crosslinker modifier. 一种弹性体组合物和引入具有改善性能的烃聚合物改性剂的方法。组合物包括弹性体、填料和硅烷官能化烃聚合物改性剂(Si-HPM)，Si-HPM适
