Embodiments of the invention provide an impact modified composition comprising ethylene/α -olefin interpolymers. The ethylene/α -olefin interpolymers are characterized by an average block index, ABI, which is greater than zero and up to about 1.0 and a molecular weight distribution, Mw/Mn, greater than about 1.3. In addition or alternatively, the block ethylene/α -olefin interpolymer is characterized by having at least one fraction obtained by Temperature Rising Elution Fractionation (''TREF''), wherein the fraction has a block index greater than about 0.3 and up to about 1.0 and the ethylene/α -olefin interpolymer has a molecular weight distribution, Mw/Mn, greater than about 1.4. |
