Claim Text:
1. A propylene-based impact copolymer (ICP) comprising: a polypropylene homopolymer having an Mw/Mn within a range of from 3.0 to 5.0; and within a range of from 10 wt % to 45 wt % of single-reactor propylene copolymer based on the weight of the ICP, wherein the propylene 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 copolymer having a Mw/Mn within a range of from 3.0 to 9.0 and a Mz/Mw of less than 3.0; the propylene-based impact copolymer having a melt flow rate (230° C./2.16 kg) within a range of from 10 g/10 min to 50 g/10 min and an elongation at break of greater than 60%.
