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.
A composition comprising:
An article comprising a first elastomer, a second elastomer, a first hydrocarbon polymer additive, and a second hydrocarbon polymer additive, wherein the first elastomer is natural rubber, the second elastomer is polybutadiene rubber, the first hydrocarbon polymer additive is a C5 aliphatic resin, and the second hydrocarbon polymer additive is a dicyclopentadiene (DCPD) resin or an aromatic pure monomer resin;
