Abstract
Elastomeric compositions containing EPDM elastomers are provided, the vulcanizates of which show substantially improved adhesion properties with good dynamic ozone resistance, superior aged fatigue life and high resilience. The EPDM used is of high molecular weight and has a non-conjugated diene content of at least 6 weight percent preferably at least 7.5%. The composition also contains highly unsaturated elastomers, such as natural rubber and polybutadiene, as the additional elastomeric components.
