An elastomer comprising units derived from ethylene, a higher alpha-olefin having from 3 to 10 carbon atoms and a diene having a Mooney ML (1+4) 125° C. of from 20 to 120 and an ethylene content of from 40 to 80 wt % and a diene content of from 0.5 to 10 wt % is disclosed herein. The higher alpha-olefin forms the balance, wherein from 60 mol % to 100 mol % of the units derived from the higher alpha-olefin comprises units derived from 1-octene.
