Abstract
A composition comprising (A) from 10 wt % to 90 wt % of a polymeric ethylene ionomer; (B) from 10 wt % to 40 wt % of a propylene component including at least one propylene based polymer having a propylene content of at least 50.0 wt %, based on the total weight of the propylene based polymer, and a melt flow rate from 0.5 g/10 min to 200.0 g/10 min (according to ASTM D-1238 at 230° C./2.16 kg); and (C) from 5 wt % to 20 wt % of a crystalline block composite.
