Patent ID: 8785554

Claim:
A composition comprising: A) a first crystalline alpha-olefin based polymer wherein the polymer is polypropylene; B) a first crystalline ethylene based polymer wherein the polymer is polyethylene; and, C) at least one crystalline block composite having a Crystalline Block Composite Index of 0.1 to 0.9 comprising: i) a second crystalline ethylene based polymer; ii) a second crystalline alpha-olefin based polymer wherein the polymer is polypropylene and iii) a block copolymer comprising a crystalline ethylene block and a crystalline alpha-olefin block wherein the crystalline ethylene block of the block copolymer is the same composition as the crystalline ethylene based polymer in the block composite and the crystalline alpha-olefin block of the block copolymer is the same composition as the crystalline alpha-olefin based polymer of the block composite wherein component C) is present in an amount of from 0.5 wt % to 15 wt % based on total weight of the composition.
