    摘要： The present invention provides an elastomeric composition processable in a curable, filled rubber formulation. The composition comprises a halogenated interpolymer of a C4 to C7 isoolefin and from 3 to 20 weight percent alkylstyrene and comprising from 0.2 to 2 mole percent haloalkylstyrene, a Mooney viscosity less than 37, a number average molecular weight less than 270,000, a weight average molecular weight less than 470,000, a z-average molecular weight less than 700,000, and a branching index (g′) from 0.4 to 1.1. Also disclosed are a method of making a cured, filled rubber article, comprising compounding the elastomeric composition with filler and curative, processing the compounded composition to form a shape of the article, and curing the composition to obtain the article in the formed shape, as well as a tire comprising an innerliner made by the method.

    摘要： The invention includes select blends of elastomeric compositions of at least one halogenated elastomer and at least one other elastomer to impart certain properties to articles made from those select blends. For example, the at least one halogenated elastomer may be at least one halogenated butyl rubber, at least one halogenated star-branched butyl rubber, or at least one halogenated random copolymer of a C4 to C7 isomonoolefin derived unit, such as an isobutylene derived unit, and at least one other polymerizable unit, such as methylstyrene. The invention also includes methods to improve the brittleness point of articles made from those select blends.
