Claim Text:
1. An elastomeric composition comprising (i) at least one elastomer; (ii) at least one filler; and (iii) at least one silane-functionalized hydrocarbon polymer modifier (Si-HPM) wherein the Si-HPM comprises an interpolymer comprising at least one piperylene component, at least one cyclic pentadiene component, at least one aromatic component, and optionally at least one monomer chosen from limonenes, pinenes, and amylenes, the Si-HPM further comprising at least one functional group comprising a silane structure; wherein the modifier has a glass transition temperature of from about 60° C. to about 100° C., and wherein the interpolymer, prior to functionalization, has a weight average molecular weight of 2500 to 25,000 g/mole, a number average molecular weight of 900 to 3,000 g/mole, and a softening point from 40° C. to 160° C.
