Abstract
The invention provides a composition comprising a first composition comprising the following: A) a first ethylene/α-olefin interpolymer that has a weight average molecular weight (Mw) greater than 90,000 g/mole and a MWD less than, or equal to 3, each as determined by conventional GPC; B) a second ethylene/α-olefin interpolymer; and wherein the first composition has a number average molecular weight (Mn) less than 10,000 g/mole, as determined by conventional GPC; and wherein the α-olefin of first interpolymer is the same as the α-olefin of the second interpolymer.
