More Information
Summary:The invention provides a composition comprising the following: A) a first ethylene-based polymer, formed by a high pressure, free-radical polymerization process, and comprising the following properties: a) a Mw(abs) versus I2 relationship: Mw(abs)<A×[(I2)B], where A=5.00×102 (kg/mole)/(dg/min)B, and B=−0.40; and b) a MS versus I2 relationship: MS≥C×[(I2)D], where C=13.5 cN/(dg/min)D, and D=−0.55, c) a melt index (I2) from greater than 0.9 to 2.5 g/10 min; and B) a second ethylene-based polymer; and wherein the second ethylene-based polymer has a melt index (I2) from 0.1 to 4.0 g/10 min.
