    Abstract: The improved green strength, green elongation, and green relaxation properties of isobutylene-based elastomers at elevated temperatures along with improved aging and barrier properties are achieved by blending semi-compatible, semi-crystalline copolymers with the isobutylene elastomers. The semi-crystalline copolymers are typically copolymers of ethylene and an alpha-olefin having from 4 to 16 carbon atoms. The improved properties are maintained in subsequent rubber compounds containing said blends and are particularly useful in tire and pharmaceutical container applications.
