1. A composition comprising:
a) from 50 wt % to 95 wt % of a propylene homopolymer; b) from 3 wt % to 48 wt % of a bis(sulfonyl azide) coupled ethylene/C3-20 α-olefin copolymer having an I10/I2 from greater than 7.5 to 15.0 and a density less than 0.90 g/cc; and c) from 2 wt % to 15 wt % of a block composite comprising (i) a soft copolymer comprising propylene and greater than 10 mol % ethylene, (ii) a hard polymer comprising greater than 90 mol % propylene, (iii) a diblock copolymer having a soft segment and a hard segment, wherein the soft segment is the same as the soft copolymer and the hard segment is the same as the hard polymer.
