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