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.
