    Abstract: An elastomeric composition is disclosed. The elastomeric composition includes, per 100 parts by weight of rubber (phr): about 5 to about 40 phr of styrene/butadiene copolymer; about 60 to about 100 phr of natural mbber or polyisoprene; a curative agent; an antioxidant; about 1 to about 20 phr carbon black; about 5 to about 40 phr plasticizing agent; about 40 to about 80 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 ethyl-ene-propylene-diene terpolymer, butyl mbber, poly(isobutylene-co-para-methylstyrene) and poly(isobutylene-co-para-methylstyrene-co-isoprene) terpolymer. The polymer based on ethylene-propylene-diene terpolymer, butyl mbber, poly(isobutylene-co-para-methylstyrene) and poly(isobutylene-co-para-methylstyrene-co-isoprene) terpolymer may be functionalized.

    Abstract: Described herein are hydrocarbon polymer modifiers for use in various applications. The hydrocarbon polymer modifier comprises a cyclic component, and has a glass transition temperature and Mn defined by the following two equations: (1) Tg≥95-2.2*(% H Ar); and (2) Tg≥125−(0.08*Mn) and an aromaticity content of less than or equal to 6 mole %, wherein Tg is glass transition temperature as expressed in ° C. of the modifier, the % H Ar represents the content of aromatic protons in the hydrocarbon polymer modifier, and Mn represents the number average molecular weight of the hydrocarbon polymer modifier, and the cyclic component is selected from the group of a distillation cut from a petroleum refinery stream, and/or C4 C5 or C6 cyclic olefins and mixtures thereof, and wherein the hydrocarbon polymer modifier has number average molecular weight (Mn) of between 150 and 800 g/mol. The hydrocarbon modifiers are particularly useful in high Tg applications where compatibility with the polymer systems and/or ease of manufacturing are desirable.
