Abstract:
Embodiments of the invention provide a class of ethylene/α-olefin block 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, M/M, greater than about 1. 3. Preferably, the block index is from about 0. 2 to about 1. 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, M/M, greater than about 1. 4.
