摘要： The present invention is an elastomeric composition having a primary rubber component, and an elastomeric component. More particularly, in one embodiment the elastomeric composition has from 50 to 95 phr natural rubber as the primary rubber component, from 5 to 40 phr of a copolymer of a C4 to C7 isoolefin and a para-alkylstyrene as the elastomeric component, and from 0 to 40 phr of polybutadiene as a secondary rubber component. In one embodiment, the copolymer includes a terpolymer of isobutylene, para-methylstyrene and para-bromomethylstyrene, wherein the parabromomethylstyrene is present from 0.2 mol % to 3.0 mol %. Further, the composition desirably contains carbon black. The compositions are useful for tire treads and tire sidewalls having improved winter wear properties such as high DIN abrasion values and improved Tangent Delta values. The compositions are also useful in any application where high damping and high abrasion resistance is desirable, such as in hoses, belts antivibrational mounts and shoe soles.

摘要： The present invention includes compositions suitable for tire treads or sidewalls and other articles where abrasion resistance and flexibility are desirable. The invention includes a tire tread or sidewall made by combining a filler; a sulfur cure system; optionally at least one secondary rubber; and at least one halogenated terpolymer of C4 to C8 isoolefin derived units, C4 to Cl4 multiolefin derived units, and p-alkylstyrene derived units. Examples of suitable fillers include carbon black, silica, and combinations thereof. The present invention also includes a method of producing an elastomeric terpolymer composition comprising combining in a diluent C4 to C8 isoolefin monomers, C4 to Cl4 multiolefin monomers, and p-alkylstyrene monomers in the presence of a Lewis acid and at least one initiator to produce the terpolymer. Examples of suitable initiators include cumyl compounds and or halogenated organic compounds, especially secondary or tertiary halogenated compounds such as, for example, t-butylchloride, 2-acetyl-2-phenylpropane (cumyl acetate), 2-methoxy-2-phenyl propane (cumylmethyl-ether), 1,4-di(2-methoxy-2-propyl)benzene (di(cumylmethyl ether)); the cumyl halides, particularly the chlorides, such as, for example 2-chloro-2-phenylpropane, cumyl chloride (l-chloro-l-methylethyl)benzene), 1,4-di(2-chloro-2-propyl)benzene (di(cumylchloride)), and 1,3,5-tri(2-chloro-2-propyl)benzene (tri(cumylchloride)); the aliphatic halides, particularly the chlorides, such as, for example, 2-chloro-2,4,4-trimethylpentane (TMPCI), and 2-bromo-2,4,4-trimethylpentane (TMPBr).
