Abstract:
A propylene-based impact copolymer (ICP) and composition including the ICP, the ICP comprising a polypropylene homopolymer and within the range of from 10 wt % to 45 wt % of propylene copolymer based on the weight of the ICP, wherein the copolymer comprises from 20 wt % to 44 wt % ethylene, 1-butene, 1-hexene and/or 1-octene derived units and from 80 to 56 wt % propylene-derived units based on the weight of the propylene copolymer, the propylene-based impact copolymer having a Melt Flow Rate (230° C./2.16 kg) within the range of from 10 g/10 min to 50 g/10 min and an Elongation at Break of greater than 70%.
