Abstract: Rubber compounds may comprise: an epoxidized polypentenamer rubber (CPR) and/or a hydrolyzed epoxidized CPR; and a filler comprising silica particles. One nonlimiting example is rubber compound comprising: phr to 90 phr of a styrene-butadiene rubber (SBR), a natural rubber (NR), and/or a butadiene rubber (BR); 10 phr to 50 phr of a epoxidized CPR and/or a hydrolyzed epoxidized CPR; and 10 phr to 200 phr of a filler comprising silica particles, wherein the SBR, the NR, the BR, the epoxidized CPR, and the hydrolyzed epoxidized CPR combined equal 100 parts. Rubber compounds comprising epoxidized CPR and/or a hydrolyzed epoxidized CPR; and a filler comprising silica particles may be useful in tire compositions.

Abstract: The present invention provides an elastomeric composition comprising: at least one first elastomer; at least one first hydrocarbon polymer additive; and at least one second hydrocarbon polymer additive; wherein each of the first hydrocarbon polymer additive and the second hydrocarbon polymer additive is selected from the group consisting of: C5 aliphatic resins, C9 aromatic resins, mixed C5/C9 resins, pure aromatic monomer resins, dicyclopentadiene (DCPD) resins, aromatic modified cycloaliphatic resins, coumarone indene resins, rosin resins, rosin esters, terpene resins, modified terpene resins, terpene phenolic resins, and hydrogenated resins thereof. The composition may further comprise a second elastomer which is immiscible with the first elastomer.
