Compositions of low and high melt index ethylene/alpha-olefin interpolymers for improved mechanical properties

Abstract

A composition comprising at least the following: a first composition comprising components a and b: a) a first ethylene/alpha-olefin interpolymer comprising an I2≤100 dg/min, and a density ≤0.880 g/cc, and b) a second ethylene/alpha-olefin interpolymer comprising an I2>100 dg/min; and wherein the first composition meets the following relationship: y<1.26 ln(x)−3.90, where y=weight ratio of the second interpolymer to the first interpolymer, and x=the I2 ratio of the second interpolymer to the first interpolymer; and wherein the composition comprises ≥60 wt % of the sum of the first interpolymer and the second interpolymer, based on the weight of the composition.
