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 polymers with the isobutylene elastomers. The improved properties are maintained in subsequent rubber compounds containing said blends and are particularly useful in tire and pharmaceutical container applications.
