    Abstract: An elastomeric composition is disclosed. The elastomeric composition includes, per 100 parts by weight of rubber (phr): about 60 to about 100 phr of polybutadiene having a cis-1,4 linkage content of at least 95%; about 5 to 40 phr of a styrene/butadiene copolymer; a curative agent; an antioxidant; about 50 to about 80 phr hydrocarbon resin; about 100 to about 140 phr silica; about 1 to about 20 phr silane coupling agent and about 5 to about 30 phr of a polymer selected from the group consisting of ethylene-propylene-diene terpolymer, butyl rubber, poly(isobutylene-co-para-methylstyrene) and poly(isobutylene-co-para-methyl-styrene-co-isoprene) terpolymer. The polymer based on ethylene-propylene-diene terpolymer, butyl rubber, poly(isobutylene-co-para-methylstyrene) and poly(isobutylene-co-para-methylstyrene-co-isoprene) terpolymer may be functionalized.

    Abstract: This invention relates to a dicyclopentadiene (DCPD)-based resin functionalized with groups capable of reacting with silica or carbon black for use in high performance tires and a preferred method of preparing the functionalized resin comprising ruthenium-catalyzed ring-opening cross metathesis. The functionalized resin may comprise the reaction product obtained by contacting a polymer comprising units derived from (DCPD) and a vinyl monomer or vinylene monomer in the presence of a metathesis catalyst, wherein the vinyl monomer or vinylene monomer comprises at least one of the following functional groups: a silyl group, a siloxy group, or an alkoxysilyl group. This invention further relates to a tire tread composition comprising the functionalized resin and which exhibits enhanced durability, traction, handling, and extractability properties.
