The elastomer polymers, including ethylene, alpha-olefins and vinylnorbornenes, have improved extrusion properties compared to ethylene, alpha-olefins, non-conjugated diene elastomeric polymers including other non-conjugated dienes other than vinylnorbornene, Properties, and improved curing properties. The elastomeric polymers comprising vinylnorbornene generally have a branching index of less than 0.5. |
