Provided herein is a polymer comprising from about 65 wt % to about 90 wt % based on the total weight of the blend of an ethylene α-olefin elastomer having either no crystallinity or crystallinity derived from ethylene, having greater than about 75 wt % units derived from ethylene; and from about 10 wt % to about 35 wt % based on the total weight of the blend of a propylene polymer having about 40 wt % or more units derived from propylene, including isotactically arranged propylene derived sequences; wherein the ethylene α-olefin elastomer and the propylene polymer are prepared in separate reactors arranged in parallel configuration.
