CURABLE ETHYLENE-ALPHA OLEFIN-DIENE ELASTOMER

摘要

There is provided a composition having improved co-curing characteristics with highly unsaturated diene rubbers comprising an ethylene-alpha olefin-diene elastomer preferably produced in a gas phase process and an accelerator; a blend of the gas phase ethylenealpha olefin-diene (e.g. EPDM) composition with a highly unsaturated diene rubber, both of which find particular utility in tire sidewalls; and a process for co-curing a shaped elastomeric body utilizing the composition to a rubber article such as a tire carcass having at least one highly unsaturated diene rubber component.
