Patent number: 8362184Abstract: Embodiments of the invention provide a class of mesophase separated butene/?-olefin block interpolymers with controlled block sequences. The butene/?-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 1.4. Preferably, the block index is from about 0.2 to about 1. In addition or alternatively, the block butene/?-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 butene/?-olefin interpolymer has a molecular weight distribution, Mw/Mn, greater than about 1.4.Type: GrantFiled: January 30, 2009Date of Patent: January 29, 2013Assignee: DOW Global Technologies, LLCInventors: Gary R.
