Patent number: 8921491Abstract: Embodiments of the invention provide an impact modified composition comprising ethylene/?-olefin interpolymers. The ethylene/?-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/?-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/?-olefin interpolymer has a molecular weight distribution, Mw/Mn, greater than about 1.4.Type: GrantFiled: September 28, 2009Date of Patent: December 30, 2014Assignee: Dow Global Technologies LLCInventors: Kim L. Walton, Theresa J. Hermel-Davidock, Henry G. Heck, Phillip D. Hustad, Mark T. Berard
