Abstract (en)
[origin: WO2007106881A1] Embodiments of the invention provide a class of propylene/a-olefin block interpolymers. The propylene/a-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<SUB>w</SUB>/M<SUB>n</SUB>, greater than about 1.3. Preferably, the block index is from about 0.2 to about 1. In addition or alternatively, the block propylene/a-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 propylene/a-olefin interpolymer has a molecular weight distribution, M<SUB>w</SUB>/M<SUB>n</SUB>, greater than about 1.3.
